I have miscarried on october 2013. i had a d& c the 17th of oct. recieved my first period nov. 23rd . now 12-29 & no period neg p test. could i be pg?

Possibly.: Assuming your period on nov 23rd was a real period and that your periods are regular (sometimes they're not after a pregnancy loss), you'd expect a period in december but you haven't had one...If you had unprotected sex, it's always safe to assume the possibility and i would get tested. Were you trying for pregnancy? If not and not pregnant, consider contraception. Get on a prenatal vitamin btw!
