I have had the same issues and have been trying for about a year but if u don't have reg men's trails it's hard to know when u'll ovulate so I went to the dr and they started me on provera to help induce a menstral and then clomid to help induce ovulation. This is my first time trying this but I have been doing a lot of reading and many women have had success with my similar symptoms of irregular menstrals. I'm hoping for the best. Good luck to you and hope this helps.
Sorry for the typos...I was voice texting! ;p
