Trying to get Pregnant

Leslie

I’ve been off my depo since May 2020 & my period isn’t until 2days I’m starting to have cramps, I’ve had sex the day before Ovulation & on Ovulation day & I woke up with cramps heavy but mild to very little, & my stomach is sore. Alittle Nausa. Could it be my period or because I’ve never had these before...I usually don’t!
