Hey, I'm TTC but I have polycystic ovaries so my cycle is irregular. Had my cycle 3 months in a row last year, oct-dec. My period was to b here already but it didn't come. I spotted today...brown. Nothing else. My friends and boyfriend kidding bout me being pregnant but I'm wondering if I am, don't want to take the pregnancy test and be disappointed again. Anyways how can I get pregnant on my own with polycystic ovaries? Any tips,and advice wud b appreciated.
