Pergnant and what to do

I think I'm pernant but I don't know if I should tell my ex that I am or not . he cheated on me and now he's with his mom with his new fat g\f. should I tell him that he his one more kid or leave it be?

I think you should tell him that you are or think you are, even if he has a fat girlfriend. or not he should now that you are and it might or be his. That is a good way to tell him that you are pregnant.I got pregnant by my ex and he left his big fat girlfriend. and came back to me and now we are going to get married in 3 years. I hope the best for you and I will be praying for you ok, good luck with this you are going to need it big time ok. BABYGIRL_86
