Normal to feel this way?

I’m 15 weeks pregnant with my second baby. Lost my first at 28 weeks due to a rare disorder. That was in 2016 and I told my husband multiple times I didn’t want anymore kids. He did, and decided one night not to pull out. Of course I got pregnant with this baby. At times I’m happy, other times I wish I wasn’t pregnant and really don’t want this baby. It doesn’t help that I work long hours and probably won’t be able to spend a lot of time with the baby after the maternity leave ends. By this time last time I’d bought all kinds of things for baby, this time I haven’t bought a single thing and don’t have a desire to. Any mamas going through this right now?
