Help, please!

Amy
My story is kind of a long one so I will shorten it up. This past November I had surgery to remove 6 vaginal cysts (and I've never felt the same since down there) then this past May I was put on a stronger BC to help remove a very painful ovarian cyst. (I have a cyst making body, or so my OBGYN says) Well I finished that month of BC, we waited one full cycle and then began trying for a baby. So far we have been unsuccessful. My period is so irregular, I went from a 28 day cycle to now having a 19 day cycle and my period lasts for 9 days. I have NO clue when I'm ovulating and it is so stressful. Is there anything I can be doing differently? I did start tracking my BBT. But I'm hoping to find some help on regulating my periods so that I have a better idea of when I am ovulating. Thank you in advance!
