Wanting a baby

I don't know if this is a bit weird or not but my SO and I are getting married in Deceber (9 months away) and he's said we can start ttc after the wedding but I'm so broody! Every baby I see makes me so jealous! At first I thought I just had baby fever as everyone around me is gettin pregnant but it's been about 5 months since I started feeling this. I've even bought some baby clothes 😁 has anyone else experienced this and how did you stop yourself thinking about babies all the time?
