Am I pregnant

 I had a surgical abortion in September due to reasons I don't want to discuss, I was having unprotected sex which I totally understand was wrong, I have been getting my periods monthly since. In November I had my period from the 13th till 18th. When should they come this month? Last week I had some ovulation pain !! I had unprotected sex on the 19th of November and my boyfriend didn't ejaculate at all, we wore a condom though! Today I have been so tired and had thrush the past couple days, I have been really swollen and my boobs feel full! Is this because my periods are due or is there a chance I'm pregnant! I get so worried I can't help but be scared.
