I have seriously irregular menstrual cycles. I can go about 2 to 3 months without getting a period and when I do I get extremely bad cramps to the point of passing out and the period lasts for upto 7 days, on a quite heavy flow. I don't really have consistent eating habits could this be the main cause? I'm really scared at the fact that because I don't have a consistent cycle at all (I'm lucky to get it once every other month), does that mean I won't be able to get pregnant?
What can I do to make it a more reliable cycle, because I honest to god can't tell when I'm due on, and it's even worse being sexually active with a boyfriend because there's continuous pregnancy scares.
