Light blood after sex

So me and my bf just finished and he noticed there was blood on the condom then I went to go to the bathroom and peed when I wiped I noticed light pink ish blood on the toilet paper I have a pad on and there’s a bit of light pink blood on it, is there a possibility that it’s my period?? I did get some cramping right after as well and still have some now the blood has lightened up since we finished and I was suppose to start my period today as well but never got it
