hello so, yesterday i got a bad migraine, sweats, vomiting, diarrhea, chills and shaky.. that lasted for less than an hour... i have only had this happen once before and that was last year about a week or two before i found out that i was pregnant.. now i had my period (or what i thought was my period) and my doctor told me it wasnt my period it was implantation.. well last week my period was 2 days late i took a test and it said negative.. my period showed the next day but im wondering maybe would it be a reoccurance of what happened when i got pregnant the first time?
