Hello and welcome, Please do not worry. Pregnancy causes absent periods. The only time you bleed due to pregnancy is a miscarriage [ or abortion]. So if you had a normal period before this then pregnancy is not likely. However it is better to get a urine pregnancy test done to rule it out. Other causes of repeated frequent periods are fibroids, hormonal imbalances and dysfunctional uterine bleeding [ where no cause is found]. If you continue to have heavy and frequent periods despite a negative pregnancy test, it is better to get an evaluation from a gynecologist to determine the exact cause so that proper treatment can be given. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
