TW - ambivalence

If you feel strongly that women shouldn't have anything other than positive feelings about a pregnancy, please turn back now.

I'm going to be 32 this year. My huband and I just got married in March. He is in law school, so he hasn't been bringing in any income for close to 2 years. Currently, I am the sole financial provider. He will have an associate position over the summer, but that's it until August 2020 after he passes the bar. This arrangement is fine for the 2 of us, but it will be a very tight situation. I wanted to do the SAHM thing for the first year, but that is an economically unsound idea. Loss of income + the loss of my health insurance. There is a possibility husband would be able to add me to his student insurance. This mixed with everything else that comes with a baby has really been weighing on me. I have been crying a lot wondering if moving forward with the pregnancy is the right decision. I just feel so, so sad. Husband wants the baby 100%, but wants to support me. Is anyone else confused, having mixed emotions or negative emotions, or feeling ambivalent? I feel so alone.
