Worried about finances

I want this baby more than anything in the world. I would never take it back for a split second. The worrier in me is just speaking very loudly now. Between doctor and hospital bills for myself, then in the future doctor bills and daycare for the baby, I'm just worried we can't afford everything this precious baby needs. We make okay money, nothing great, and I have a lot of other payments and bills I make. My fiancée and I have separate accounts so I worry I'll be left with the bills. I started a baby savings fund and hope in 6 months we have at least a little something to help...I'm about 15 weeks now. And no, our pregnancy wasn't exactly planned, so we didn't have a lot of savings beforehand. I'm just ranting I guess. I'm just so stressed and worried.
