It's has been two weeks since my fiancé and I last had sex and I started to get morning sickness, back pain, and my stomach started to hurt and was hard. But I'm now on my 9th day of my period! (NEVER has it been this long!) So I went to the Dr. And I had gained around 13 lbs since the last time I checked my weight. So she ran a pregnancy test, but it came back negative, but positive for a bladder infection. But the infection could be overruling my pregnancy hormones if I'm early (according to my Dr.).. Any suggestions? It's just stressful not knowing.
