So, I'm getting a little concerned... TMI ahead but my period was expected the 19th which started yesterday. I have been so nauseous like I literally just wanna throw up all day long. And this started right before I started bleeding. I just feel so sick to my stomach.. and then when having sex, I got this weird tingly stabbing pain in all of my stomach. It wasn't severely painful but enough to where it made me wanna stop.. has anyone ever experienced this or nausea during their period? I've NEVER had this issue so I'm worried.. also I'm really not bleeding very heavy. It's pretty light which is also unusual because I bleed pretty heavy the first few days normally.
