Hello, I am 21 and have a 14 month old son and don't plan to have another child for 4 years. This month has been weird. I had a UTi infection that required Antibiotics. I also missed a day but doubled up the next. This happened twice. Now it is 5 days before my Period is due and I am cramping really bad and spotting. I don't cramp but the first day of my period and now it has been 3 days. Could this be my period or am I pregnant? I took a test but it was to early and of coarse it said no!
