I feel like shit. What do I do?

Wiktoria

My period started on 3/11/22 and today is the final day. I have been so emotional and sad and I’m so much pain with cramps for the whole time. It’s supposed to be my last day of my period and I’m feeling like shit. I have a stomach ache and I nearly threw up taking my iron and folic acid tablets. There’s no way that I’m pregnant as I always use protection with my boyfriend and I’ve literally just had my period. One side of me is anxious and wants to take a pregnancy test to just double check but the other side of me thinks that’s fucking ridiculous. Last night I had some sort of white pasty type stuff come out of one boob and got hella panicked. My family have been ill with a virus (not Covid) and I think I’m starting to catch it a little bit. I have been getting hot flushes and cold shivers throughout the night and have been waking up in the middle of the night for no reason whatsoever.

Please advise me whether it’s just a stomach bug type thing or if something is up?
