Pregnancy - 13 weeks

I'm now 13 and a half weeks pregnant so i'm out of my first trimester. I have terrible morning sickness, well all day sickness really and just a terrible gag reflex. I can't eat or smell food until after mid-day without the risk of throwing up. I'm still has tired as ever as my body is adjusting to the pregnancy and everything. I'm not sleeping well, and I think thats just because of all the stress which is going on in my life. I know i need to sleep because in a few months that will even be off the cards as my belly grows bigger. I have also had this last week Heartburn and indigestion, which I have never had before in my life. Also I have been having  round ligament pain, it's not too painful but I can feel a sharp pain usually on the right side of my belly. It normally only happens when I have been sitting around and get up or do some sudden movement.It usually just means my uterus is strenghing for the baby, which means my belly is growing and starting to show more. I'm now just over 38 inches (which is just over 1 inch growth in a week and a bit) and seem to be just growing more and more. Baby is around around 2 1/2 to 3 inches long and weighs about 7 ounces, she he/she is growing. I still don't 'feel' pregnant. I know that I am now but I just can't feel it, I can't put my hand on my bump, I haven't felt my baby move. I just don't know how to feel. I'm still scared that i'm not going to be able to love my baby, that when I look at him/her all I will see are the regrets, miss opportunites and hurt that has come because of him/her. I don't want it to be that way, but i'm scare I will. I don't know what i need to do to convince myself otherwise, how do I know that I will love this baby. I'm still figuring alot of things out and i'm hoping by the time my baby is born my feelings will be completely different to what i'm feeling now. Because right now I just feel regret, like i have made a huge mistake in deciding to bring up this baby, to be a 16 year old single mom.
