Irregular periods

Courtney
I stopped taking my BC last September, in anticipation of TTC.  For 6 months, my periods were crazy heavy, but regular. Since March, I've been anywhere from 20 days to over 60.  I had a weird little 2 1/2 day wimpy one (finally) a couple weeks ago, and then it abruptly stopped. I haven't had a positive test or LH surge since, but today I started cramping, and spotting (brown).  It's started coming out in a grainy clot-like  texture. Has anybody else experienced this?  TTC is even harder when I can't even tell if I'm having a legit period or not.  
​Also, did anyone else get acne after stopping BC?  Acne has been a real battle since January for me. TIA for your input!!
