I haven't read the whole thread, just the first few posts, so sorry if I repeat a lot of what might have been said.
I was 17 when I found out I was pregnant. It was scary to find out at first, and I was petrified of what my parents would say. I was quite surprised on their response tbh. They were very calm when I told them, although still shocked.
I'm now 22, my daughter is 4 in December, and I am very happy. I'm no longer with my partner, but that was a decision I made myself when my daughter was 8 months old. I've been doing part time college for the past 2 or 3 years, and starting again in a couple of weeks, and I also work part time. Money's tight, but at the moment, I'm renting out so all my money's going there, and I'm actually moving back into my mum's next week just so I can save money.
At the end of the day, it is your decision (sorry know it's been said a few times). Have input from your partner, family, friends, doctor etc, but it's down to you. It is a big decision because it's so life changing, but I think deep down you know what you want to do, although you may not know it yet. Doubts, fears and worries will always come into play because it's such a huge step, no matter how old you are, but probably more so when you're still fairly youngish yourself.
If you feel you can't speak to someone that you know, try speaking to your doctor or a support group that you could phone. Even if you're not asking for advice from them, least it's you getting all your thoughts and feelings out into the open to someone, and it may help you realise how you feel about it all.
If you do decide to have this baby, you can still go back to education, and do the midwife course you wanted. And we all want to give our children the best possible things in life, but the most important thing they need is the love from their mother.
Sorry if that seems a bit patronising or condesending or anything, but my brains a bit meh at the moment, so I can't think properly lol.
