Is it possible to still be pregnant

Troy • 23 years old
My bf and I do not use condoms ever and when he cums he doesn't pull out..I don't use bc or plan b's.( also I have mild dysplaysia) I had sex all throughout the month of September before during and after ovulation all times unprotected and  he didn't pull out. This month October I had wat I think is my period on the date expected however it only last 2 1/2 days and seems as tho my symptoms were greater than the usual..definitely have excessive tiredness peeing and nausea Is it possible I could still be pregnant? Not to mention one of my coworkers told me I was glowing wen I went to work today (he barely sees me only on weekends) so could I still be pregnant?
