To keep or to terminate?

I’m 6weeks pregnant. Informed my fiancè about it last week & he wanted me to terminate the pregnancy. Reasons - he is not ready & unstable. His point, It is an early stage of pregnancy so terminating it is fine. 🙄 I’m a career woman in my 30s. It has been giving me a lot of stress then I began to spot/bleed at week 5. Doc puts me on 2 weeks progesterone to support the pregnancy.. I’m so confused & lost. #pleasehelp
