Yes tell your Dr that's a bit early. To be swelling like that
My grandmother always told me if I started to swell to tell your doctor asap because it could mean you have some type of toxic poisoning. She lost a baby to it. But dont stress to much untill you talk to your doctor because being pregnant makes you sensitive to salt as well. I have had mild swelling due to my salt intake.
I would definitely bring it up. I didnt start swelling like that until the end and it was in the summer.
