Went though ABVD, DHAP, BEAM and radiation to the mediatinum. In remission for the 2nd time. I was supposed to be ammenorrhiac and continue to have regular periods, what are my chances of concieving or even ovulating if I continue to have my period?

Radiation to the mediastinum should mean above your diaphragm so I don't see that being an issue with regard to your reproductive system. If anything were to make you ammenorrhiac and/or infertile it would be the chemo.

The biggest factors are age, drugs and dosages. Some women will experience chemo-caused ammenorrhea for a year or more, only to have their periods return. I don't know statistics, but the fact that you're having regular periods is not a bad sign, that's for sure.

However, it does NOT ensure fertility either. Beyond a drug like Procarbazine, which you didn't receive, the biggest chemo threats are the alkylating agents, which I don't think you received either, followed by something like doxorubicin, which you DID receive (in the ABVD).

If I were you I wouldn't be too encouraged by your regular periods. Not trying to be an ass here, just realistic. I mean it's better than them not occuring, but for many women it's probably quite often misleading, and a source of false hope that I imagine would be heartbreaking.

Personally I don't know how to interpret your hormone test results, so I can't say whether they are encouraging in the face of the prior chemo treatment. perhaps someone over at conceivingconcepts.com might have an idea?
