If medical abortion has done at 14 weeks and i bled for a month, can the baby still survive? keep getting very faint positive hpts

Unlikely: You may wish to get a blood HCG test done to see the level. Persistent slight elevation may mean retained products of conception and require a D&C. It would be prudent to consult your gynecologist.

One Whole Month???: You shouldn't have bled for a month.You also should have been examined if you bled for more than 1-2 weeks. It's very unlikely that anything is alive in there at this point. There may be some retained tissue that lets go of a little bit of the stuff that causes the test to be positive.At this point you should see a doctor to find out why you are bleeding and how much blood you have lost.Don't wait
