so my period was due Friday and it didn't come, me and my SO had sex then afterwards I felt crampy and I had bleeding which what I thought was the beginning of my period but then I noticed it wasn't much at all and my cramps stopped. then the bleeding stopped. then now today I'm having some light spotting with no cramps at all. I have the paragard iud, I have tested thursday, friday, and today and all were negative. I've been feeling nauseous and I have been eating all day and i feeel so hungry! like I haven't ate nothing! anyone has any advice would really help😭I don't know what's going on.
