Weird symptom: My fingers lock for less than a second too often, especially after doing any work involving water (showering, washing something, etc.). Has anyone else also faced this or any other weird symptom?

Hi! I'm 21 weeks along, FTM. Recently my fingers lock randomly for a few milliseconds every now and then. Especially if they've been in water for some time. Is that normal? My doctor gave an additional magnesium supplement for that but does anyone else also face this. It just seems so weird.

Pregnancy seems to have a lot of weird and unpopular symptoms. What were yours? Why does no one talk of those or warn us of those? Some days are just not beautiful while being pregnant. They're barely manageable!
