Help !!

Could I be pregnant I got my period last week it lasted a week but it was light but I wasn’t spotting and the 4th day it was a pinkish color like my period was ending but the 5th day it was back red and I’m having pains in the middle part of my stomach and the last time my boyfriend went in raw but I made him put a condom on was November 25th a day after I ovulated and I got my period in December on time too and I did the pee in a cup and use salt but I didn’t get no reaction and I used early morning pee too I have a 28 day cycle and I’ve been stressing
