Not sure how to feel

I'm not sure how to feel about finding out I'm pregnant. I want it but my boyfriend does not, So that makes me worry about it. I started a medicine and apparently it makes pregnancy happen lol this was not planned at all. This is my third pregnancy but both previous ones I lost. 2014 I miscarried at 13 weeks and this past January I was just under 6 weeks. I'm happy, scared, excited, worried, and idk what else.
