HOW DOES IT WORK?

Genevieve • Mother of 2 princesses 💞, not a TTC, just tracking my ovulation. From Nigeria 🇳🇬, A stay at home mom. Love making friends, will be glad if I got friends in here 😂.

I need a help on how this works. Is it according to the month you had sex, or the month it was confirmed that one is pregnant?. Like one had sex on May and conceived in June. Which month now do I use for the calculation. Am really confused, and am so eager to know please.

so eager to know please.
