TMIIIIIIII !!!!!

So not sure if any of you would know . Im not sure if this is from having sex with hubby ( just so you guys know hubby and I baby danced last night & now it’s 9 pm today) or if this is from a bacterial infection I was just diagnosed with? My doctor did prescribe me antibiotics the day before yesterday and I did just start taking them yesterday. Btw AF is due sometime between the 2nd & the 5th.
