Frustrated. Help!

I MC at the end of July. It took 8 weeks to get my first cycle, I showed positive OPK & Hubby and BD like crazy! After my TTW I showed all negative tests, so I figured that maybe I didn't ovulate. No biggie--I was just ready to try again the next cycle. Well...now I'm on CD 45 and I still have no sign of AF and I'm past the point of testing. Anyone else take forever to get back on track? I feel like if I don't get regulated we'll only be able to TTC once every 3-4 months! Ugh!!!
