Spotting for 2 wks straight, confirmed am pregnant possible twins c-section 7 mths ago hcg increasing normally. what are causes for bleeding? m/c?

Spotting: Spotting is relatively common in early pregnancy and isn't always a sign of miscarriage. The cervix is often friable during pregnancy, so hold off on intercourse for a week or so and see if that makes a difference. Implantation site bleeding is relatively common too. If you smoke, stop as smoking is highly associated with this type of bleeding more likely to cause a miscarriage.
