Possible ph balance issue

Does anyone know if giving birth can throw off your ph balance ? I’m 3 almost 4 months pp and I feel like every since I had my daughter things haven’t been the same as it was before I had her . There’s no itching or fishy odor , my vagina just doesn’t smell as it did before . I’m not sure if the soaps I use are affecting me now (they didn’t before I had my daughter ) or what ? 😩😏
