I was simply tracking my period not trying to get pregnant but my boyfriend and I weren't being careful and I missed my February period once I missed it i took about 6 pregnancy tests that all said negative till about March 7 so then I went to the er to see what was wrong with me and they tests me for pregnancy and gave me an ultrasound both came back as not pregnant except I had fluid in my uturues so I'm like ok I'll just relax and wait for my period come the 12th of March the day my period should start I didn't get it so my boyfriend buys me a pregnancy test and tells me to take it at a 7 eleven  when I took it it said positive.
