Had 1st miscarriage sept 3 with 2 d&c. 2nd miscarriage nov 3rd. took a home test and it's pos. what it's the likely chance i can carry to term?

Not certain: It's hard to give a definite number to estimate the likelihood of you carrying to term. However, if you get past the first trimester, your likelihood of carrying this pregnancy to term increases tremendously. My best wishes are with you.

Maybe not preg: If you had a miscarriage less than a month ago, you may still have elevated hormone levels from that pregnancy. That could be high enough to show on a pregnancy test for several months even without a new pregnancy. Give yourself a break. Wait for the hormone levels to go to zero before you try to get pregnant again.
