Worried

I am 2 days late 
I'm still having cramps and my boobs are really sensitive 
We had sex with a condom
The. He took a shower and we did it raw but he didn't come anywhere close to coming again because his mom showed up 
And I told this to a friend and she said probably not its probs just my hormones changing because I've been having a lot of sex lately 
Cuz this happened to her when she didn't get hers for the month but the coming up she did.
And idk I'm just slightly worried 
And I'm totally not TTC
