Period late

So I stopped my pills about two months ago and I was supposed to get my period on Wednesday but I haven’t gotten it. I’ve been having period cramps and spotting light red. I have also been using condoms and my bf never came in me. However, We didn’t use the condoms in the beginning of sex but I did wipe off the pre cum. I took a pregnancy test yesterday in the afternoon and it came out negative. Is there any way I can be pregnant or is it my body adjusting? Should I also take another test with the morning pee?
