Troubles

So I take my birth control to regulate my period because at one point I was getting it every other week 🙄🙄 but I had missed like 6 days so to catch up I doubled up Friday night; Saturday night and Sunday night and now I’m experiencing extreme nausea, cramps and hot flashes. I also got my period for when I was going to sleep last night but then it was gone by the time I was awake. There’s a strange smell that smells exactly like period blood.. but the is no blood..? So kinda confused 🤷🏼‍♀️
