my doctor said that I was pretty swollen at my apt yesterday and she told me to watch out for some signs that could.mean preeclamcia like constant headache nausea and stuff like that well I've been having a constant headache for 3 going on 4 days now but I'm not sure if it would be because of the weather being extremely hot or if it would be because I haven't gotten hardly any sleep or if its because of possibly preclampasia . anyone who has preclampasia have any suggestions?
