Treated like a crash

I'm 19 weeks pregnant.Yesterday around 5pm I went to an Emergency ward due to I had endless headache since the 9th October reason why I went only yesterday it got worse, I tried drinking water and taking a Panado as it's safe to do so .. when I arrived there 2 nurses were yelling at me why I only came that Time , I was trying to explain my reasons but they were busy shouting I tried telling them politely that they are making it worse .. because my head was paining so much . I was crying trying to explain my self . Until I stopped explaining ... just crying . Being pregnant and younger than them does not give them right to disrespect patients . Worst experience of my life .
