Hi Mirrie,

I had exactly the same problem as you. I would start very slight brown spotting about 7 days before my period would start and we never found an explanation for it. The same thing happened during our fresh IVF cycles and I thought it might have been due to the Crinone in the fresh cycle or the progesterone in the frozen cycle.

During the frozen cycle in which we were successful, I once again had the brown spotting and thought it was all over. But we got our BFP and now we have our lovely daughter.

The brown spotting continued through the pregnancy until I had a big bleed at 10 weeks. Fortunately it wasn't a miscarriage but we never found the source of the problem. The brown spotting continued, sometimes turning red and finally at 14 weeks, the obs found that I had a cervical polyp attached to my cervix.

Once it was removed, all the brown spotting stopped completely. He thought that it might have grown as a result of high oestrogen levels, but they really don't know the cause of cervical polyps.

It is possible the polyp grew during my fresh cycles as a result of high oestrogen levels, but that doesn't explain the brown spotting I had before starting IVF, so not sure it is really the explanation.

Anyway, sorry for the long post. But the message is, yes, I am living proof that you can still get pregnant with this dreadful brown spotting

Best of luck with the IVF. Its a long hard road and I wish you every success.
