Preeclampsia symptoms?

If anyone here has had preeclampsia come on between 22 weeks & 34 could you please tell me what your first symptoms were? I am concerned by the sudden changes in my body but the ob said they're pretty sure it's probably just acid reflux and to take pepcid. (This was done over phone today.) I did have an appointment on Monday which some of these things had just started and the PA said please call back and talk to OB at end of the week if symptoms persist or you develop more and they would do a blood draw etc.

All my nausea and vomiting went away completely, then 10 weeks later I started throwing up after meals...not really nauseas...I've been having pain in upper right side in the front mostly but some in the back, headache and then throwing up after about 80% of the time I eat. This has all started last weekend before my appointment on Monday and progressed to throwing up every meal yesterday. No fevers, no diarrhea etc I have been having a bowel movement every day... does anyone have any thoughts or info on if this is just acid reflux and if it affected you the same way?

When I googled some symptoms *i know I know, not always a good idea* early onset preeclampsia came up and ive never known anyone who has had pre eclampsia so just hoping for some input. My blood pressure has been pretty good at every appointment so far though. Also I am feeling baby move daily so idk.
