Just found out I'm pregnant

I just found out I'm pregnant and I already have 2 kids. A 2 year old (3 in November) and a 4 month old. Please don't judge me. I'm looking for support. I couldn't get into the ob because money has been tight and it's more important for my kids to get to their appts. I'm stressed because I'm only a few months post partum. I'm 8 weeksish. My husband and I are still over the moon though. He's supposed to be sterile due to issues as a kid. But this is our second child, so I guess he's not as sterile as they think.
