Prolonged Bleeding??!

lily

I take my birth control continuously (meaning i never take the period pills/placebos) and ive had light bleeding for 11 days. i called my doctor on day 9 and she told me to stop taking my birth control for 4 days. since then, i’ve had heavy bleeding and bad cramps right on my ovaries. i read online that sometimes you can bleed from implantation of pregnancy. should i be worried since i’ve had unprotected sex in the last month?
