Birth Control :: Took ECP, Period Is 8 Days Late W/period Symptoms?

My periods are usually regular - 28 days but there are a couple times in a year where I get my period on the 21st day/a few days before or after the 28th. I last got my period on November 2 and it lasted for a week. On November 11, my boyfriend and I had unprotected sex and he ejaculated inside of me. I took the Nordette ECP (4 pills at first and then 4 pills 12 hours later) about 5 - 10 minutes after. On the 16th, I started my withdrawal bleeding. I usually get withdrawal bleeding, but this time it was a lot heavier. The first 2 - 3 days, I had to wear a pad and every time I coughed I felt blood coming out. It lasted like a period and eventually died down. It weirded me out a little because my withdrawal bleedings were usually quite light - light enough for me to wear only a pantyliner.

Last week, I got my usual PMS symptoms (slight sore breasts, a bit of cramping, and acne breakout). It has been 36 days and my breasts are back to normal, my cramping is very mild, but my acne breakout is CRAZY. Usually I only get maybe a pimple or two on my forehead but I have them on my forehead, cheeks, and chin! I've had no pregnancy symptoms whatsoever and no implantation bleeding as well. However, a few days ago my boyfriend and I had sex and my vaginal discharge was brown. I'm quite positive it can't be implantation bleeding because if it were, I should have bled a week before that.

Every time I've taken the ECP, my period is always on time. It's never been this late. I'm getting very anxious even if I have no pregnancy symptoms. My acne breakouts are usually my #1 indicator that I'm about to get on my period but it's been 8 days and still no luck! I've read around that some women really do miss a period and some can come as late as 70+ days. There's a high chance I'm not pregnant since I took the ECP in the window time and I wasn't ovulating that day, but any advice would do me well!
