I'm really sorry to hear about your situation
If you need to talk,
PM me please.
I went through the steps toward having an abortion, and decided not to go through with it, so if you have any questions feel free to ask. My advice it to stay away from crisis centers. They pop up around actual abortion clinics and try to trick you into thinking they are an abortion clinic. They then try to talk you out of your decision, and give you false statistics to make you feel like a bad person for considering abortion.
Abortion isn't the right decision for everyone, but if you feel its right for you then don't let others make you feel guilty for your decision. Their is a lot of emotional baggage that comes along with both abortion and adoption, you just have to decide which path will be easier for you to handle. For me, I also thought the medical abortion was the right way to go but it was too late for me and I think that's why I couldn't go through with it. Nurses at abortion clinics are very supportive for the most part, and are there to help you through the process. I'd recommend going to planned parenthood too, they are also there to talk through your options with you, and give you lists of places where you can go whether you choose parenting, adoption or abortion.
As for the nausea... I had it really bad also. I couldn't even keep water down. I recommend gatorade and ginger snaps, they always helped my stomach. Also, eat even if you don't feel hungry. Sometimes just having something on my stomach made it feel so much better.
I know you say that you are broke (I was jobless and moneyless also) but if you end up deciding to go through with raising a child, get on medicaid (assuming you live in the US?). It pays for everything. Even if you went to a doctor or hospital while on no insurance for something related to the pregnancy, they will still pays those bills for you. It saved me.
Good luck, and like I said... I'm here anytime to talk.
