HELP! PERIOD!

Bella
So A Few Months Back (like in February) i Had My Period For 3 Weeks i Went to the gynecologist and she did an ultrasound, and took a look inside and she said everything looked fineand  said it was probably 'Stress' she gave me Birth Control to regulate my period...And i Took The Birth Control For a Month and Stopped Using it Because it Makes me nauseous, so everything was going good until this month when i got my period the 13th and im still on my period. Has Anyone Had this happened? Im Really Scared that i wont be able to have babies since me and my husband were planing on having one next year 😭💔
