Okay, I don't know if I've posted this or not but I have this feeling in my stomach like I've swallowed chlorine water, like you know how your stomach feels when you do swallow chlorine water? Well I haven't been swimming in 3 weeks and it's been happening occasionally. My stomach just feels extremely weird and full? I'm on my "period" now. I just got off my period 8 days ago and now I'm on a much more heavier flow. I do have the nexplanon implant (since May). Does anyone else have this feeling? It really hurts
