I've been suffering from pcod since 3 months and have been using krimson 35 course since then and every time after the 21st pill that is the last pill I've got prompt periods within 3-4 days but this month I've taken my last pill on 13 th of December and have missed a single dose in between. I've had a unprotected sex with my boyfriend on 10 th December and got my hymen ruptured and have had heavy bleeding for almost 20 mins and so stopped sex. I've taken my last pill on 13 th December and missed a dose in between and yesterday night that is 16 th Dec night I've started bleeding and have had bleeding which stopped when I've woke up in the morning today and since today morning it's bee spotting whenever I use the urine. Y is this like this? Is this implantation bleeding?
