Cycle day 49 :(

Steph • 31 yrs old. After 2 losses I finally have my miracle Maverick. TTC again soon
Stopped my BCP middle of Dec 2013. Had a normal AF and now nothing. How long is this going to last??!!! Has this happened to anyone else?! When do I need to see a Dr?? I'm sorry for the rant I'm just really frusterated. I can't even try to conceive if I don't have my period. Feeling down.
