boyfriend noticed

Last night my boyfriend asked if I was on my period. And I said "no why?" And he's like "it hasn't happened in a while" which is true.. I'm on cycle day 51 of a normal 37 day cycle. I didn't know what to say, because my period has been all over the place lately and quite frankly I didn't even think about it until he said anything. I've been busy with college and working that it didn't even cross my mind. So I just said, that I bled during labour day weekend.. which is kind of true. I spotted a bit and according to glow when I look back that would've been shortly after O week. I should've just told him the straight up truth but I didn't want to worry him before I even know anything. Now I'm stressed because I think I could be pregnant but if I go test and come and tell him he's gonna know things don't add up unless I wait till around when my next cycle should be. Fuck my life.
