Sorry but my first question was not clear enough. i meant how can i get my mensral cycle to start again after failed ivf its been 2 months ? thanks.

Depends: You should talk with your doctor. Did you have regular/monthly periods before your ivf? Ivf does not routinely disrupt your periods after the first 1-2 months following treatment. Your doctor would probably want to consider blood tests (eg hcg, estradiol, progesterone) and/or ultrasound to decide what to do next (if anything at this point). Good luck!
