Popping sound when I pee


So I’m currently 5 weeks 5 days pregnant and I’m kinda worried. For the past day every time I pee I hear and feel some type of air/pop come out from my vagina. My obgyn won’t see me until I’m 10 weeks. I’m scared like crazy because I’ve already had 2 missed miscarriages this year. I heard a pop like this with my 1st pregnancy and I went to the hospital they couldn’t explain it. Anyone know what this is? Is it normal in early pregnancy?
