tingling lips

Tyler • Hi all, my name is Tyler I am newly married to my husband of 6 years. We just got our BFP!!!!
Hi everyone, I am 36 weeks and I have started getting tingling lips ( on my face just FYI) the past few days. I am wondering if anyone has had this before? I am super uncofterbul and now adding this to the mix just adds more stress... 
Thanks for any help :)
