So, I have recently found out that I AM expecting a few days ago. I went in because of some vaginal bleeding and it wasn't time for my menstrual cycle. Well, they did a blood test and we came to find out that I was indeed a week and a half pregnant. Basically, I guess what my question is... "How long does implantation bleeding occur?" Also, if this ISN'T implantation bleedng, what COULD be wrong? Should I be worried. Im going to go ahead and schedule a Dr.
