Is this normal?

Anyone else ever have sex on the days they KNOW they're fertile and just kind of feel "different" the next day? Like your brain seems to focus more on your pelvis, you're a little sore, maybe a little bloated kind of just feel sick almost the next day ? My fiance and I had sex on the first day (Monday) and the fifth day (yesterday) of my fertile window. Just curious if this is a purely mental thing or if my body may be onto something, or I'm just crazy.

Baby dust and hopes for a BFP to everyone TTC who reads this!

Also, anyone ever feel like this and find out they got pregnant that cycle?
