Anyone know of a way to get you period started.

Me and my husband are TTC #2. I have been off my BC since May and have had normal periods since June but I haven't had a period since August...... No not pregnant all BFNs ?. Anyway I just want to be able to track when I ovulate. Sony suggestions on how to start my period up without having to go to the DR. Also what are my odds for getting pregnant without my period?
