Hi! I am ready. 22 years old. I had regular 28 days cycle of my menses which never last more than 5 days never had any problem with my flow or period color. But from july I am having irregular periods which too shocking and uncomfortable for me because I never had any issue before. I took a dose of Ecp (contraceptive pill) on 6 june which are 2 tablets. And after that I took another dose on 6 july. I got my periods on 12 july which lasts 5 days and were normal by flow and color. I then got my first irregular period on 24th july which were brown in color and too light and lasts 5 days. After that I got my periods on 23rd august. A normal period. And again on 7th september I got them for 5 days. Then on 23rd sept. I took Contraceptive pill on 30th september but The same dates are for october I just god my periods after 12 days. I am really worried what's happening. .i went to the gynaecologist and explained her every detail. She did my CBC, Serum B HCG, and ultrasound. My hemoglobin is 9.5,ultrasound was clear. No PCOS. HCG was negative. She did not explained me anything. She just said we will do your day 2 hormone test. Can anyone please tell me? Should I be worried? Or they'll normal after some time? Or is it a side effect of contraceptive pill?
