Deciding on baby #2, advice

So my hubby and I currently have a 21 month old. We both decided that we were going to try for #2 when our first is 2. Since having my first, my thyroid has been so messed up and I am seeing a doctor

In the next few weeks. I haven’t a period since August. At first I was excited because I thought I could be pregnant but then I got to 30 days late and every test was negative. So today I started bleeding a little and I came home from work and told my hubs that I think my period started and he said “good”. I thought we were both on the same page about wanting another baby. Being that we said we’d start trying around the end of the year anyways. I asked him, do you not want another baby? And he said no i do. I just don’t want to have a baby next year. That made me really sad because up until a week or so ago he was all gung-ho about it talking about it with our friends. Then boom a light switched. So After I got out the shower he was like what’s your problem and I told him my feelings were kinda hurt because he knows I’ve been having baby fever for like 6 months and we both agreed. I asked him what changed in a week. And he said that his mom And stepdad booked a hotel room in Biloxi next year for cruising the coast and he wants to go. ( he has a race truck but it only has 2 seats) so I said well what about our son? He said he already got that taken care of he’ll ride with his mom and dad. So now he doesn’t want to have another baby because of a fricken car show. My obgyn said with my hypothyroidism it could take me a while to get pregnant. I found out about that this week and then my husband sprung that on me tonight. I don’t know what kind of advice I’m looking for here. But I’m just upset. My husband spends every extra cent he has to that race truck. It consumes 40% of his life and now the stupid truck is Going to determine when we get to have another baby. I know that sounds stupid but I’m literally so mad. I’ll be 28 next year and while that’s not old I told him I wanted to have our last child by the time I turned 28. All of our friends had kids in their early 20s so their kids are 4-7 and my husband gets like jealous of their lives cause their kids are older and they can do more and we have a toddler. But he was the one that wanted to wait. Waited 5 years after he proposed to let me plan a wedding. I’ve always been go with the flow with him and all his wants and he’s trying to make me feel bad for wanting another baby. Am I wrong?
