Beyond confused!

I am new to this site but could really use any information, support, and advice that you have. I am about 8.5 weeks pregnant and very confused about what to do with this baby. I have always wanted a family with lots of children but I'm worried that it's too soon and I won't be able to support the child. A little background info: I just turned 22 years old and my fiance is 24 years old. We have only been together for about 10 months but it was one of those things where we just knew we wanted to be together forever from the beginning. However, now I am even second guessing that and have considered breaking things off, but, I know that 90% of that is because of this baby and just being so stressed out that it's really taking a toll on our relationship. This pregnancy was not necessarily a mistake, but, we weren't actively trying to conceive either. I had gotten pregnant back in September but miscarried in late October and I have been wanting a child even more so after that miscarriage but, we're not ready. When I say we're not ready, it's because we're not financially stable. I know that practically no one is really 100% financially secure before starting a family, but, we're not really secure at all. I have family that would help us out if we do have this child and keep it but, I don't want to be relying on my parents for money and security. That's just not who I am. My fiance REALLY wants to keep the baby and was very upset when I first mentioned an open adoption. However, he has now comes to terms with it and says if it's really what's best for the child and our relationship, he will support that decision. I am just so confused because I feel like after losing a baby a few months ago and letting this pregnancy happen and even looking forward to being pregnant again (I knew it wouldn't take long because my family tends to be very fertile and I did nothing to prevent it), I should be over the moon excited about this pregnancy. And when I look at the ultrasound picture, I want to keep this baby more than anything. But then reality sets in and I realize that we are in no way shape or form going to be able to take care of this child on our own without a lot of outside help and I feel like giving this child away for adoption is the best thing for the child. I know that I'm still very early in this pregnancy and have a lot of time to think about it. But, I just really need some advice because I want to have time to come to terms with my decision and accept it. I don't want to be struggling last minute to make a decision and feel pressured one way or the other. When I say we're not financially stable - my fiance has a job as a cook. It was supposed to be full time and has really been about one day a week. NOT good. I have basically been in retail management since I was 16 and have a lot of skills that make me qualified for many positions, but am currently unemployed. It's very hard to get a job right now and on top of that, I just had one that I had to quit. I started a job right when I found out I was pregnant and had to quit a few weeks into it because I have been SO sick. First, I had a high fever and horrible cold. And now, I'm nauseous all day, every day and haven't been able to keep anything down. It wasn't fair to the company and I felt horrible, so I just had to part ways and am now looking for a job again (even though the sickness has not eased up, but I'm hoping it will by the time I find a job). We are both hard workers and willing to put in a lot of time and effort with a job, but things just haven't been working out. My fiance is also in the Army National Guard so he has his once a month weekend drills and whatnot. Now, we could move elsewhere (when we get the money) and he could have a Monday thru Friday job with the National Guard and we would have a lot more money & security. But, all my family lives here and I haven't fully decided if it's worth it or not to leave my family and be any where from 12 - 24 hours away from them (by car) during my first pregnancy and with a baby (provided we keep the baby). My family has said they will help us out financially if we stay here, but not so much if we leave. Which, is understandable. So I'm very torn. This would be so much more easy if we weren't financially stable AND I knew we weren't fit to be parents yet (maturity level, personalities, etc). But, I know we would both make GREAT parents and would love this child to pieces. We both absolutely love kids and it makes this so much harder on me. Ugh, I'm so sorry this has gotten so long. I just really need some opinions and advice because I am LOST. If you couldn't tell, haha. Thank you in advance to anyone who took the time to read this and can weigh in with some advice!
