Last comment...promise. If you ever have any questions about your c-section, you can send me a private message and I'd be happy to try to help.
OH, by the way before getting pregnant I had heavy periods, and since having my c-section more than a year ago, my periods are lighter. I don't know if yours will be, but just be careful with losing so much blood.
You may have had a small clot that passed. The same thing happened to me 2 times after my c-section. If you are still bleeding, I doubt you are pregnant. You would have to be ovulating, and if you're continuously bleeding I wouldn't think an egg could implant. I suggest taking it easy, no matter how energetic and fine you feel, I was on the go from the beginning with doctors appointments and my new found energy, and that's what caused my problems, plus shortly after the first month was over I was exhausted all the time from life with a newborn. Just take it easy, and if you are bleeding enough to fill a pad in an hour go to the doctor ASAP.
