Cold tingling lips?

Hi I’m sort of new to TTC. I tried a year ago when I was about 70 pounds heavier but I wasn’t ovulating according to my opk tests. This month we decided to try and I ovulated on the 25th and we tried a few days prior and following. Now this week I’ve been super tired, I have sore breasts and the weirdest thing is that my lips go cold and tingly, then that instantly makes me feel dizzy. I’ve never experience ANYTHING like this in my life and it’s the weirdest sensation. Anyone else ever feel this? My blood pressure has been good and I eat high protein stuff about every two hours because I do weight watchers so I don’t necessarily think it’s a blood sugar thing. Just wondering if anyone else had advice?
