Pregnant? Please help

Me and my boyfriend have had sex multiple times this month, one time was on a 27% day, but he didn't cum in me, we used condoms everytime, one time he did cum in me but with a condom on, as far as we know none of the condoms have broken. Glow predicts me to get my period today but it's normally 28 days and today is 27, my other app says monday. Yesterday and today I had a nosebleed , and I heard that is an early pregnancy sign, do you think im pregnant or fine since I used a condom?
