Wednesday I was suppose to start my period. I have a very heavy period typically. Wednesday it didn’t come and yesterday it also didn’t come. Half way through the day I wiped and there was just about a quarter size of pink, (no red blood). I assumed my period would start in the next 24 hours because of how heavy my flow is. I still have yet to start my period and I haven’t had any pink since. Then this morning I got nauseous and vomited. I took a test and it appears negative still. Thoughts?
