Am i weird...

I want to buy a fetal Doppler to have for my next pregnancy.. I had one but the ear phone type I've always wanted the one where you can we the actual heartbeat go up. I'm a mommy of a 3yr old. Mc in June last yr.so TTC my rainbow bby??? But I really have bay fever and have noticed myself looking for maternity clothes & fetal Doppler's.... Is that odd???
