Lol i ate then used my Doppler

I’ve heard baby’s heartbeat and just finished my dinner which was a grilled cheese and salad when my hubby decided he wanted to hear baby (I’m just coming to the end of my first trimester) so I said it’s unlikely because I’ve just ate soooo much food but I’ll try and all you could hear was “PFFFFT” “FRRRT” and gas inside of me. My belly would rumble and the Doppler would go crazy loud from it it was so funny 😂 hubby still doesn’t understand that I can’t hear a heartbeat so early right after a big meal, it was literally like 2 minutes later so can any of you ladies please give him some reassurance that it is because I’ve just eaten baby isn’t clear and it’s weird noises lol
