Should I Contact My Midwife????

I'm just over 38 weeks pregnant, and I've been feeling sick to my stomach everyday since the 3rd of September, my midwife says it's just heartburn and told me to take Zantac when I feel sick. Which I do and it doesn't help at all!

And today on top of feeling sick to my stomach I have a major headache that won't go away with Tylenol or rest.

My midwife said to call her if I have a headache that won't go away but the last time I did that she prescribed a script and that didn't even work! I've been tested for preeclampsia 4 times already and I don't want to again due to all of the results coming back negative! I've also had a stress test done in L+ D and baby and I were fine...

I'm not sure what I should do! I need help!!!!!!!!!!!!
