So upset!! Please help

Hello all,

I had terrible cramps on cd 10 in my ovaries (so bad it woke me up at 5 am). The same day I started light brown spotting and now I am on cd 13 and I am spotting pink... any idea why this is happening? Did it happen to you before?

I had spotted before but never that early in my cycle. I am very upset I have been waiting for so long for this month because I need a summer birth (due to my job). I have no one to talk to and crying here because of disappointment in myself. I just hope that it is pre-ovulation spotting. I haven’t ovulated yet have been taking opks and I don’t have any cysts that I know of!
