You're just getting started
Good news: most of what helps at this stage is simple, and you don't have to do everything at once. A preconception visit isn't required, but it's the easiest way to catch the few things worth handling before you start.
Trying to conceive usually takes time. Around 80–85% of couples conceive within a year, and most of the rest do with help.
The foundations with the strongest evidence: a daily prenatal with folate, a medication review, vaccinations, knowing your cycle, and not smoking.
A preconception visit is a normal appointment with your OB-GYN or primary care doctor to review health history, medications, and anything worth checking first.
- Strong evidence Start a prenatal now. 400 micrograms of folate plus iodine and vitamin D, ideally a month before you try. What to look for.
- Strong evidence No smoking, and no alcohol while you're trying. Your partner should quit smoking and cut back on drinking too.
- Moderate evidence Keep caffeine under about 200 mg a day. About two 8-ounce cups of home-brewed coffee. What's in what.
- Give your partner a head start. Sperm take two to three months to develop, so changes now pay off later. What actually helps.
- Want to go further?. Everything else, sorted by strength of evidence.
A prenatal vitamin
Start one now, ideally at least a month before trying. Look for 400 micrograms of folate (folic acid or methylfolate both count — more if MTHFR has come up for you), 150 micrograms of iodine and vitamin D. Many prenatals skip choline, which is worth checking for.Medications and supplements
Bring every prescription, over-the-counter medicine and supplement to your first visit. Some need switching months before you try, and a few of the ones people stop out of caution are ones to stay on: see medications and trying to conceive.Vaccinations
Rubella and varicella immunity, plus routine vaccines, are usually checked at a preconception visit.Knowing when you ovulate
Regular cycles of roughly 21–35 days usually mean you're ovulating. The fertile window is the five days before ovulation plus the day itself — sperm survive several days, the egg survives about one. Cycle apps mostly do arithmetic on past cycles and predict the actual day less than half the time; LH tests pinpoint it, and cervical mucus warns you earlier. Apps, sticks, mucus and temperature, compared →How often, and when
Every one to two days through the window is what ASRM's guidance points to. "Every other day" is inside that range, needs no tracking at all, and is far easier to sustain. Timing, lubricants, and the mistakes that are easy to make →The two weeks after
Implantation happens 6–12 days after ovulation and hCG only appears afterwards, which is why early tests and symptom-spotting can't tell you what you want to know. What's actually happening, and when to test →Health conditions
Thyroid disease, diabetes, high blood pressure, and a history of pelvic infection, surgery, or endometriosis are worth raising now.Your partner's health
Smoking, heat exposure, certain medications, and some health conditions affect sperm. It's half of the equation and rarely mentioned.Optimizing beyond the basics
A Mediterranean-style diet, omega-3s, vitamin D, sleep, and (for some) myo-inositol or CoQ10 all have research behind them — mostly early or mixed for fertility, and good for your health regardless. See what actually helps, sorted by evidence, and how to choose a quality brand.Calming the body
Caffeine under 200 mg a day, a daily stress practice, sleep, and an anti-inflammatory eating pattern. One randomized trial in IVF found a structured mind/body program helped; the evidence is early. See caffeine, stress, and inflammation.
- Is there anything in my health history or medications that we should address before I start trying?Bring the whole list. Some prescriptions need switching months ahead, and a few that people stop out of caution should be continued.
- Should I be taking anything beyond folate, based on my history? I've read about methylfolate versus folic acid, vitamin D, omega-3s, and CoQ10.Bring the research as questions. It gets you a real answer and keeps what you take on your record.
- Can we check my vitamin D and thyroid levels now, so I can correct anything before trying?
- Given my age and history, how long should I try before coming back for an evaluation?Under 35, guidelines suggest an evaluation after twelve months of trying, or sooner if there's a known reason to (irregular cycles, a history of pelvic infection or surgery, endometriosis, or a partner with a known issue).
Plus 2 more on your appointment checklist.
Start a daily prenatal with folate (folic acid or methylfolate both count) now if you haven't, and make any medication changes your doctor recommends.
Under 35, guidelines suggest an evaluation after twelve months of trying, or sooner if there's a known reason to (irregular cycles, a history of pelvic infection or surgery, endometriosis, or a partner with a known issue). Put that date on your calendar so it isn't a decision you have to make while discouraged.
When you reach it, move to the next Path: We've been trying.
At this stage a second opinion is rarely needed. The exception is if you have a known condition (irregular or absent periods, endometriosis, PCOS, a history of pelvic infection, or a partner with a known issue) and you're told to 'just keep trying' without any evaluation. Guidelines support earlier evaluation in those cases, and it's reasonable to ask why not.
