Just got a positive. Anxiety through the roof.

So my husband and I have been trying to get pregnant for a year and a half now. After many negatives this morning I woke up to a positive! I can’t believe it. I thought this would never happen for me. After sitting in the bathroom in unbelief I was so excited! Now I’m laying in bed nervous as hell that I’m not ready to be a mom. My husband is still in school and I don’t know how we are going to do it financially. Any advice? I haven’t told my husband yet. Wanting to wait until monday until I get a blood test.
