Quoting *Momma Mandy Lynn*:" SO and I have been TTC since december but nothing has happened. We had an abortion 2 years ago because ... [snip!] ... been in so much pain the last 2 weeks and SO and I haven't had sex since a couple days after my last AF which was Feb 3rd. "
I don't think you have anything to worry about. It took my husband and I 8 months to finally conceive when we officially began trying. Also, my friend's periods are never normal, so she never knew when she was ovulating. After a few months of trying, she conceived. Although your period isn't heavy or last 5 days, does not mean you can't conceive. Just keep trying and don't worry.
I hope everything works out for you.
