So I took to pregnancy test (came out negative) because I have been having back pains since thursday of last week to tonight and I had unprotected sex both Saturday, sunday and Monday morning tge week before last... not only that but I had a really bad migraine this last sunday evening in to Monday morning... then I went out to eat at PF Chang's and I must of had food poisoning or something... cause I threw up all random at like 1:00am monday night.... and yesterday I felt nauseous and tired and just slept half the day... and today I worked and I was super hungry, ate and before that I felt nauseous and im a normal being and this doesn't really happen to me... and last night I had a dream of having a baby and I wasn't even thinking of it till I had that dream and woke up this morning :/ idk whats going on with me and im not sick I know forsure... but maybe I should get a blood test instead. Any suggestions, advice, and or opinions? Oh and im on the nuva ring birth control but my period ended right before the three days of no protection so I had it out like 7 days before that... (did it everyday though and yes he did in me...)
