I'm 4 weeks, 6 days today. Found out I was pregnant last Thursday. On Saturday evening, I had red spotting in my  nderwear (no cramping). Brown spotting after that then it stopped. Went to the doc on Monday and they checked my levels and again on Thursday. Friday they called and said my levels are increasing nicely. I'm still really worried. This is my third pregnancy and I've never had bleeding. I have an ultrasound 7-9 but it seems like FOREVER. Anyone have any similar stories with (hopefully) happy endings?
