pregnancy scare help

I keep posting about my worry about being pregnant because I’m so ducking scared. Basically my boyfriend and I had unprotected sex twice in a week two weeks ago. He was certain he didn’t cum in me and pulled out a good 4 mins before he cummed but I still went to get the morning after pill straight after the next day on both occasions. This results in my hormones being fucked up. I’m now one day late for my period and am getting strange kind of discharge but I don’t know if it’s normal and I’m assuming the worst. Someone help me I’m very scared.
