TTC fatigue

Jashley
So my fiance and I are TTC.  This is our first month trying. Ive have a miscarriage before in October'16. It was a lot to handle. So we finally decide to try again. We started at the peak of my ovulation this month where on the ever app said 27% or 33%. Now i had a bout BV and was on the antibiotic and we did have sex because I caught it early and sex wasnt painful or anything it wasn't full blown so I thought it would be okay. I finished my meds and i was wondering is it possible to concieve on BV meds? Could it affect the baby or cause me to miscarry again? Lately Ive been extremely tired like so tired i just fell asleep at work! I was looking at the screen and went to sleep. I get 8 hours of aleep usually but ive been having to nap when i get home because im just that tired usually for 4 hours wake up for a few hours and back to sleep until its time for me to work. And i have been using the bathrrom alot.  But those are the only symptoms. Could i be with child?
