I'm a 28th cycle day and I ovulate on cycle 14 but I knew I started ovulating last night so we got busy, me and my partner used pre-seed and it work really good for us✨😌 I HOPE it sticks and I PRAY I get my BFP. More along to the story.. when we had sex maybe an hour or two later I felt nausea but it wasn't bad it was there though, when we did it again I kept feeling nausea (NO IM NOT ALLGERIC TO HIS SEMEN)... this afternoon I felt as if I was having period cramps it was mild😩 every since then I haven't felt anything else.
