Feeling really unwell

I have been feeling unwell the last few days and extremely tiered , I’ve put it down to managing a 1yo and working 30+ but today has been awful I have had the odd headache and my bp was down on my last app but midwife wasn’t concerned.

Today though I have been really dizzy my head has been pounding I’ve even been seeing stars and I have ate and drank as much as I possibly can!!

So I rang my midwife and she told me to call the day assessment unit as she suggested i needed bloods done ,m.

Well..... I rang and spoke to a very unhelpful woman who basically said that because I am only 21+2 that it was unlikely to be serious and to go to my local birthing unit tomorrow morning ,

I feel so confused as one midwife is saying get checked and another brushing me off , am I being over the top ? I just don’t feel right !!
