Anyone see flashes but have no headaches?

Currently 33 weeks, and my bp has been perfect through my pregnancy. I don’t have a headache.

I was feeling slightly nauseous this morning, but that’s about it. Called my doctors office but had to leave a msg.

I was standing in my kitchen when I suddenly thought I saw two flashes. I thought maybe lightning outside since it’s been raining but It definitely was different.

I’ve also had a few spasms in my back, but that’s probably just because baby boy is so active in there.
