Pregnant and Scared.

So here's the thing, I want to be a mom. I honestly and truly want to meet a mother and about 5 years ago I had a miscarriage. It destroyed me and my boyfriend and almost our relationship. All the changes my body went through after and all the emotions I had was a lot to handle but we got through it. Fast forward to now, we were intimate a few days ago and in the heat of the moment I told him to just do it. Cum in me and well he did...checked my eve calendar and saw we did it on a low risk day but I'm still nervous. I asked yesterday..."baby, what if I get pregnant...?" He said, "well then, I guess we're having a baby..."

So here's my thing:

Financially, we are on the struggle bus but I'm scared that if we have the baby and then...we're worse off. Idk I'm ranting, I want this but I'm scared I'll lose it again. I'm just venting...what do you guys think?
