Needing advice

So I found out I’m pregnant which is a blessing but I just had a baby in September of 2017 Handsome little boy he will be 5 months on the 19 of this month. I wasn’t planning on getting pregnant it kind of just happened. No I wasn’t on birth control because I’ve done some reading on the long term effects of it. I have however been using condoms with my S/0 of 3 Years. I also have a 4 year old daughter. I’m not ready nor am I in the financial state to have another child at the moment in the future but not now. I don’t believe in abortions , adoption I was considering but dad doesn’t agree he said he would want to see the baby all the time. I’m not sure how far I am. I’ve been sick since I found out I can’t eat , when I do I throw everything back up. I have this constant nauseated feeling all day in my stomach I throw up at least 5 times a day. My other pregnancies wasn’t like this at all. I’m not sure what I should do I haven’t made a doctors appointment I don’t know why but I’m kind of scared to face my midwives knowing I just had a baby 5 months ago. Any ladies been in this situation before that can give me advice I don’t really have anyone else to turn to. I’m 21 I live on my own work and go to school.
