Leah, I have been pregnant a few times, with each pregnancy I have had pains at that start, implantation can cause pain, I think (although dont remember clearly) that my pains lasted for at least the first few months and to be open about it, I would get horrendous cramps in my uterus whilst haveing an orgasm int he early stages too.
I have 2 children, my eldest has never met his biological father as we too split up. I then had another son and since having him have had an abortion. You will always survive and get by, I dont really think money is an issue, there are plenty of loving parents who cant provide everything they would love to for their children. I think the bigger issue is, are you ready to raise a child on your own. Its hard, hard work and you will be putting your life on hold. If I could go back in time, I really truely would not have made the same decisions ( I love my children very much and would never give them up btw). I would have waited till I was really truely in love and possibly married for a couple of years before I had kids.
