You got a positive pregnancy test — congratulations. Now the practical question hits: what do you do with the fertility supplements you’ve been taking? Prenatal vitamins and TTC formulas are not the same thing, and the rules for each are different. Here is how to sort your shelf, what to ask your OB or midwife, and what your partner can stop.
This is educational, not medical advice. Your prenatal care provider should review every product you take once you’re pregnant.
1. Prenatal vitamin vs TTC formula: they play different roles
A prenatal vitamin is designed for pregnancy itself and is typically continued throughout. A TTC formula — like AGO Mom — is designed to support egg health and reproductive wellness before conception. Once you’re pregnant, its job is done. That’s why the default for most women is: keep the prenatal your provider recommends, and stop the TTC-specific product until your provider says otherwise. See AGO Mom vs prenatal vitamins for the difference in detail.
2. A simple shelf sort after a positive test
| Product type | Default after a positive test |
|---|---|
| Prenatal vitamin | Usually continue; confirm the brand with your OB or midwife |
| TTC formula (e.g., AGO Mom) | Stop and bring the label to your first prenatal visit |
| Herbal cycle or hormonal-balance blends (e.g., AGO Eva, Eva Herblux, Mau Nguyet Da) | Stop unless your provider specifically approves |
| Uterine wellness formulas (e.g., AGO Tumor) | Stop and discuss your fibroid plan with your OB |
| Single add-ons (CoQ10, inositol, extra vitamin D) | Ask before continuing; some are reviewed case by case |
When in doubt, pause and ask. A few days without a non-essential supplement is rarely a problem; taking something your provider hasn’t reviewed during early pregnancy can be.
3. What your partner can stop
Male fertility supplements like AGO Dad and AGO Sea Oyster are designed to support sperm health during the trying window. After conception, many men simply finish the bottle or stop. If you’re planning another pregnancy later, it’s worth knowing that sperm take about 72–90 days to develop, so he’d restart roughly three months before trying again.

4. Special cases: IVF, FET and medicated cycles
If you conceived through IVF, a frozen embryo transfer or a Clomid or letrozole cycle, your clinic likely has you on medications (such as progesterone support) with a specific schedule. Follow the clinic’s instructions to the letter and ask them — not the internet — before restarting any supplement. If you’re in the two-week wait, don’t add anything new without your clinic’s OK.
5. If you’re not pregnant this cycle
If the test is negative, most people continue their TTC plan and review it after about three cycles. Our guide on what to check after 3 months helps you decide whether to adjust, and fertility supplements to get pregnant covers the category.
