D.F.
This is a case for a Doctor. I had 5 periods (or what I thought were periods) with my second child. Found out at 5 1/2 months I was pregnant. Delivered at 7 months. Turned out I had FULL Placenta Previa. Lesson learned "When in doubt get it checked out". Glad to say my daughter survived and is a healthy young woman today. But never wait.
