Hey honey, I can tell you with no hesitation that dealing with the loss of your baby due to complications and natural death would be so much easier to bear and deal with than knowing that you took his/her life by choice. Now knowing this does not make your situation easier and I really feel for you, I think you just need to take some deep breaths and do something nice for yourself. You are 17 weeks along, you are able to find out the sex of your baby at this stage, here is a link to a website that is really good at showing you week by week what your baby's development is,
www.pregnancy.org/fetaldevelopment ,you cannot take your child's life into your own hands out of fear of the unknown...I had two kids from two dads before I got married, my oldest daughters dad is still not involved in her life and she is 7, I too came from a broken home, what I have learned is that I now get to "break the cycle", I get to make better memories for them than I had, I get to protect them from dysfunctional environments, I get to love them the way I always longed to be loved, you cannot control the dads actions but you can choose your own, you can give this baby a WONDERFUL life, do not rob yourself of the joy that is within your womb because of his selfishness...being pregnant in a "perfect" situation can be tough, the hormones, the body changes etc...in your situation, the same one I was in years back, there is so much more going on than that...I think you are just experiencing "jitters", you are going to be a great mommy, you will be perfectly able to provide for yourself and this child, I have no doubt that you will meet a wonderful man who will CHOOSE to be a father...Just hang in there, I am here for you and I want to assure you that keeping this baby is the right thing for you, if not then you would not have been chosen to be his/her mommy!! I am so sorry that you are having a rough time, I truly am, just try to keep your head up and know that you are not alone...Love Meg
