Some one please give me some imput on this...?

the last time a HPT told me negative i was two months pregnant... i fear i might be pregnant again and don't know about it... (i would love another baby but right now is not a good time) i have been safe with BC and condoms but we all know that it is not a full 100 % safe... should i take another HPT or just wait it out and see what happens.. i take care of myself as it is already and i am still takeing Prenate DHA vitamins (they are the best vitamins ive ever taken) my stomach is getting bigger and my cravings are strong like the last and my belly is even geting hard... my husband wants to wait , i fear he is affraid i really am he changes the subject every time i bring it up... what do you think... im on BC so i dont wether my periods have stoped or what its a shot kind
