Is 3 a crowd

If you are pro life or against abortion please do not read nor add advice I am not trying to upset anyone I just want the right advice. I am 5 weeks pregnant with my 3rd kid. I'm really confused on rather to abort or not. I have a 6 month old son and a 6 year old daughter. I am not in the best financial situation and I hate my job! My boyfriend is totally against having abut her baby but I do know if I choose to have the baby he will support me, considering he was against me having our son. I'm so confused HELP!
