I got my period about 5 years ago. It has always been very light, crampless and 3 days max. It started getting irregular and i would bleed for a day, nothing for a second day, then bleed a third day and it would be very light. They would also be a couple days late. Recently my periods have been very late every other month- last time it was 8 days. Cramps have been unbearable and I have thrown up multiple times. Theres a very heavy flow and it gas been getting worse for the past few monhs. My mom has had ovarian cancer and her biological mom died from it so im not sure if it could be related to any of that? Please comment what you think.. thank you!
