I normally have heavy periods, but its been two months since the last one. I've had intense stomach and pain and some nausea. Could I be pregnant?

Possible pregnancy. When a woman misses 2 periods it is possibly pregnancy, so check a pregnancy test. Otherwise likely caused by hormones being off, so a period if coming will be heavier than usual. Thyroid problems, stress, gaining or losing weight can cause a woman to miss a period or two.
