My RE’s fertility clinic says CD1 is if full flow (soaking a pad). If on Monday your full flow was before 4pm then your CD1 is Monday if your full flow was after 4pm then they would call CD1 Tuesday.

@futuremrsebc:  Sunday. When your period STARTS, however heavy or light, is your day 1. Good luck!! 🤗

But really, ovulation is about 14 days BEFORE you start your period. So my cycles are about 27 days. Ovulation day would be around day 13 for me, so I’d be baby dancing that whole week leading up to day 13, and then a couple days after just in case ovulation happened later than expected. (Except I use this method to AVOID pregnancy now.) but honestly if you make sure your having sex every other day for the week before and then a few days after suspected ovulation, there will always be sperm ready to meet the egg when it is released.

Sunday was cd1. It doesn’t matter if it was light or heavy. You started. Just some menstrual info for you since you’re ttc, the time before ovulation is called the follicular phase, the time after ovulation is called the luteal phase. Both are important not only when ttc, but in other health things too. Good luck!

I’ve recently discovered that each fertility clinic has their own definiteion of CD1. My clinic says the first FULL day of flow so if I got it in the morning, I would count that as day 1, but if it arrived any time after noon, I would count the next day as day 1.

Fertility Friend and PreMom apps count the day your period arrives as day 1, regardless of what time it arrives. 

Ultimately when you’re doing SMEP, you’re going to BD several days within your fertile window so your should be OK no matter which day you choose to classify as day 1
