Gained 3lbs out of nowhere 😭😭😭

I’m almost 22 weeks and last Wednesday was my last checkup and I was 170lbs. I checked today and I’m 173😭😭😭😭. I started at 165lbs.... where did those 3lbs come from? I haven’t changed anything and haven’t been eating more than usual🙃. This is my 3rd baby and I’ve never gained weight this fast. I’m so afraid of being unhealthy and my weight gives me so much anxiety 😭. I just wanna enjoy this pregnancy because it’s my last😞 I’m not really looking for anything to come from this post. Just needed to air out some frustration. My girl is healthy though so that’s what matters most💖! I’m just having body image issues...
