Preeclampsia question:

I’m almost 31 weeks with a healthy, normal pregnancy so far (second baby, first was normal as well)

Today I wokeup with a horrible headache that’s fluctuated but hasn’t gone away- I’ve drank probably twice as much water as normal trying to get it to go away, and about an hour ago I saw spots for about 30 seconds-a minute. I’ve also been extremely tired today, for no reason. Has anyone had preeclampsia that came on suddenly without warning/with an otherwise normal pregnancy?

* I haven’t called the hospital yet, but will. I’m just currently stuck at home with my toddler until my husband gets home (he has our car and is not reachable right now). So I didn’t wanna bother calling until I at least was able to go in if they want me to.
