so my boyfriend is in jail and I just found out that I'm pregnant with our 2 child but my 3rd and his 4th. I'm 23 yes old and he is 26 years old, I was wondering what I should do? I'm 5 weeks and 5 days and going to be a single mom if 3. I'm really scared that I'll be raising this baby on my own to. parents are not supportive of me having another baby. I have a 3 yr old Lil girl and a 7 month old Lil boy. I dont believe in giving my baby away I laid down knowing I could possibly get pregnant all 3 of my kids are birth control. any moms of 3 single how hard and what are u doing to make it easier.
