So for the past 3 days I've been having really white discharge sometimes its a lot and ive been cramping and really gassy. I had unprotected sex 3 weeks ago and when I stand up I can feel a small lump near my hip bone but when I lay down I can't feel anything. Also more symptoms are last week my lower back was starting to hurt and my nipples are sore! Do you think I could be pregnant? Please leave your opinion! I'd love to know before I waste money on a pregnancy test.
