What should I do?

Sara

Okay ladies so I got off my period June 30th and me and my fiance started doing it as soon as it went away and I've been super gassy the past couple of days my boobs are tender and this morning I woke up so nausous went back to sleep and woke up and actually threw up. I know it's a small chance it can happen right after your period but maybe I ovulated early I just need advise on if I should take a test or is it just a waste because it's probably gonna be a BFN😭
