Could I possibly be pregnant? I have a regular period, every 30 days for 7 days straight. My husband and I are trying to conceive. Sunday I started my period (2 days before schedule). Then Monday night I had severe diarrhea (going every hour to hour and a half from 7PM to 5AM) with nausea and vomiting twice. My period stopped Monday night once the nausea, vomiting and diarrhea began and just a little bit of spotting the next day or two. I had no fever, no abdomenal pain or cramps. Is it just the stomach flu going around and my could it possibly mean Im pregnant?
I think you had stomach infection not pregnancy.  But still wait for few days and confirm it by UPT test.
