I miss being pregnant

I don’t know if this is normal, but my son is 3 months old, I love him to death, he’s my whole world. But I miss being pregnant with him so much. I didn’t realize it until recently, I’ve been seeing a few friends of mine announce their pregnancies and I’m kind of jealous... it’s almost making me sad, seeing positive pregnancy tests and ultrasound pictures. My son is my first and my significant other and I plan on having at least 2 more, but we’re waiting at least 5 years before trying for our next. Is it wrong for me to be jealous and sad about other people’s pregnancies? To be honest I hated being pregnant, I hated the way it made me feel, I was sick and had hypertension, was always being sent to the hospital. But part of me missed the excitement and the little kicks and feeling my little one grow.
