Sorry to hear about your loss.
I M/C too in November and i have only just had a period (Last Friday) so it took my body 8 weeks to get back to normal and i too never had a negative test until early Jan. It takes along time around 6 weeks for you body to get back to normal but everyone is different so im guessing it is from your M/C and not a new pregnancy as you also can not ovulate until your HCG levels are back down to nearly 0.
your doctor should be takig your levels every 2 weeks after MC to make sure they go back down. my doctor followed with me until they were back down to 4. So you might want to call and speak to the nurse and let the nurse know oyur concerns. Even after a d and c, it took my hcg a month to go back below 5.
The other girls answered your TTC question.....Have you had Hcg levels drawn recently? If your levels aren't going down, like your Dr. said, you may need a D&C......your body may not have expelled everything, in which case you are at risk for infection and other problems down the road.....Have you been in contact w/ your Dr. regarding everything?
I had the same question after my m/c and I was told that you will not Ovulate (therefore cannot conceive) if your levels are not back down to 0. So my guess is, your HCG numbers are still from your m/c. Mine took over a month to get back down to 0.
Hope this helps!
First of all, I am so sorry for your loss! To answer your question, your body won't be able to ovulate again (and therefore get pregnant again) until your HCG levels are back down to below 5. However, since your levels were only up to 104, they could have already come back down earlier this month, and if so, this could be a new pregnancy. Best of luck to you!
