So we’ve been using natural cycles as contraception for the last 6 months. My cycles are a little irregular and vary between 28-35 days. We aren’t actively TTC but would both be happy if we were to get pregnant. This month it turns out we had unprotected sex once on Sat (Day 15 of cycle) and I then had confirmed ovulation on the Mon (Day 17 of cycle). I know there’s a chance I could be pregnant but anyone have experience of conceiving from sex only once in the fertile window?!
