Question! Need some advice

Jazmine • TTC baby #1 💕

AF is due May 13th so just waiting to see if she comes or not. Meanwhile I have a big cyst behind my ear and my doctor prescribed ATB for 10 days 2x/day. It’s only been 5 days after ovulation day and not sure if this month I’m pregnant or not. Should I take the antibiotics still? Or wait until I get a result from pregnancy test.
