I've been using Yasmin for how many years. But this year I've been on and off it. I took my last pill of the pack last September 14 and got my period as expected on September 17. I did not continue drinking Yasmin after. Fast forward to this month, my boyfriend and I had unprotected sex October 15 and he said that he MIGHT have pre-cummed a little inside me but immediately removed his penis right away when I felt it. There was still foreplay after and he ejaculated outside. Being paranoid, I took Yasmin as an emergency birth control. I drank the first batch of 4 pills less than 5 hours after our intercourse which was around 1230am and took the second batch of 4 pills 12 hours after at around 1230pm (although i might have taken it a couple of hours late, I was really nauseous and afraid I might puke the pills out so I waited a while). It's October 22 and I still haven't gotten the withdrawal period. I'm really getting paranoid. After How many days usually should withdrawal period after taking EBC? I'm worried my hormones might have been messed up due to previously taking Yasmin regularly which is why I can't calculate my cycle.
