Help me out

I’m 5 days late and no sign of my period yet, I had intercourse twice since my last period and it was protected and I’m pretty sure we did everything right. I’ve been experiencing cramps and sore boobs for like 3 days now. I was also worried of possibly being pregnant cause last month I got my period twice ( I think due to lots of travelling that month) and I took a test a day ago which was negative. I’m not worrying that I looked at it to early and I’m just stressing myself out. Is the cramps and sore boobs a sign my period is coming ? Also if the test was negative should I be worried I could be pregnant pls let me know cause my anxiety is killing me
