Advice ?!

Please to god don’t judge me on this yesturday I was I ablsoute agony with face pain I couldn’t eat or drink at all I still havnt anything but Iv drank today cause I know that’s important my doctor has presceibed me some meds to that normally are a risk to pregnant woman but if needed to take them and I honestley needed them otherwise I don’t think the pain would go anyway since yesturday cause I didn’t drink Iv notice bright orange discharge / blood when I wipe it’s quite a lot too more than my usual discharge is this normal if your dehydrated ? I know for a fact I am and I have made sure or tried to get some water down me to today hopefully come Monday I can finally start drinking and eating right again! But I felt baby move less today I’m 21 weeks 5 days and normally feel her kick and move around a lot but also have a anterior placenta so know somtimes I do t feel her but just has me worried w

Everytime I wipe I see that just need to know if it’s normal ( I know water is important and I can’t stress enough how much Iv been trying but the pain was absloute terrifying painful even my partner never seen me in so much pain being on labour aye 😂)
