Condom question.... Need advice... .. . .. .. ... . ...

Good evening ladies I need some advice here... I have allergies with latex so I told my partner and he bought the " non-latex SKIN condom". So my question is what are the chances of getting pregnant with the non-latex condom? ...... I've been really emotional and I've dislike my kind of food and like the food I never liked like the yolks eggs and ect...
