A few questions?

Nickie

1. Fertility friend chart says I ovulated Sunday the day I got my LH dark line surge and solid smiley face on a digital, is it possible to ovulate the day you get your surge? I thought that was more of a ‘hey it’s coming’ warning.

2. The passed 2 days, days 2-4DPO I’ve had cramping, sore nipples and sharp pains in my boobs. I honestly thought I was ovulating yesterday but FF confirmed it for Sunday. Can you have the ovulation type cramps after?
