period/ovaries after c-section

so I'm new to this and i don't see a group for c-section mom's. But everyone women has a period so maybe it can be a question answered by any.

After i had my second child (c-section) for the first time. (my first child i had him natural.) my periods became worse and now experiencing pain and swelling during ovulation. I haven't seen a my Doctor because i owe a medical bill. Than about 2 months ago i had an ovarian cyst on my right ovary. now every time I am ovulating my ovaries swell up and I'm experiencing pain similar to a period. also during my Minstrel I am experiencing extreme pain. is this normal for women who have had C-sections or for women in general?? are cyst common after c-section or swelling during ovulation?? any help would be greatly appreciated.
