Having children with the same birthdays

Alyssa

My youngest son is a year old (born July 2014). I became pregnant with him in October of 2013. Well, I just noticed I'm ovulating and I haven't ovulated in quite some time now.

Is it bad or weird that I'm terrified this might be the month I get pregnant again and will have a baby near his birthday? I don't want him to feel unloved or replaced. :(
