Advice

I'm late to come on my period. (Assuming due to stress) so my grans husband died suddenly due to heart attack last Sunday not my biological grandad but I've known him all my life so as good as. I've got no job and a load of interviews to attend so can't be home with family live 8 hour drive away. I've been feeling very down about all of it and trying to FaceTime my parents a lot and my 13 & 16 year old cousins who were with him at the time. Husband complaining about the time I am spending on phone to family like I'm not supposed to be upset right now. I also asked if he could lend me some money but no :( he then asks if I'm pregnant as I'm late is it wrong that I'm hoping not seriously frightens me if he can't support me emotionally now how can he with a baby. Trying to be understanding that he has never lost anyone before but struggling to be nice or calm about things I'm a ranting crying mess all the rime. Am I being to harsh?
