morning sickness..

So just for starters I am on the combination birth control pill . anyway I had sex the day before I ended my last pack (i had already finished my period but I was finishing the placebo pills) but i missed the first day of the next pack because my prescription wasn’t refilled. I don’t always take the pill at the same time but since it’s the combination pill i figure it doesn’t matter if it’s a few hours off. when i have sex he never cums in me he always pulls out but we don’t use a condom. I also had sex on the 27 of december but he pulled out then as well. well that day i had sex with him i was super nauseous after we ate and i ended up throwing up after dinner (I gagged myself) and today is january first and i have been sick with a cold so i woke up early to take some nyquil and right after i took it i started feeling super stomach ache and i ended up throwing up and using the bathroom and now I feel fine. it was at 7am. does it sound like i’m pregnant because that’s probably the worst case scenario for me..
