Could I be pregnant

Hello, I’m a plus size gal and have two children. Sunday I had some brown discharge, and then nothing else. Last night I went to get in the shower and the boys had left some toys in there so after undressing I bent down to get them out and blood was running down my legs. (Gross I know, sorry) So I put on a pad. All night lastnight and so far all day today nothing. I had intercourse on all of my fertile days and the day after ovulating. Could I be pregnant? Also according to glow, I’m not supposed to start my menstrual cycle until tomorrow and for the past 10 months it’s been correct never a day early nor a day late.
