Worried

I'm 10 days late my period had been pretty steady for months now I do have to admit that special someone and I have been extremely irresponsible the last two months!!!! I've put on at least 10lbs I'm scared to take another test honestly I already have a 5yr old and a set of 1yr old twins although he has no kids and we talked about the possibility in the future Im really not hoping our future plans are in play only two months after the conversation!!!!! I can only hope I haven't started due to stress but for some reason I doubt that's the case
