Could I be pregnant??

Me and my SO had sex Sunday and he came in me (he usually pulls out) I'm on BC but have been late on taking it the whole week before we had sex ( but I have been taking it Just not the same time every day)my period is due in 10 days according to glow... I haven't been feeling well and have a very thick mucus discharge that has NO smell but is clumpy And had a reddish tent to it at one time
