Baby Fever

So even before I had my son I really wanted to try for Irish Twins. I still wanted to after I had my son. Jan 30th. It was even possible because I had a smooth and quick labor with no complications and I was healing great. Then the day my son turned 6 weeks I found myself in the hospital with appendicitis and had to have an emergency appendectomy. Now it's been 3 weeks since my surgery and I'm still healing from it, feeling way better than I was but afraid to have sex. Even if I had sex now and got pregnant right away, I wouldn't be able to have Irish Twins and I would have another January baby. I want my children's birthdays spread out a little bit because my one sister had 2 April babies and a December baby. Then my SIL had 2 December babies. I don't want it like that lol. But now I'm just kinda depressed I can't have my Irish Twins and now I have to wait a few months to even try for a baby. Anyone else have baby fever after just having their bundles of joy?
