Swollen tonsils - 8weeks

I'm currently overseas in Vietnam and have woken up with a really sore and swollen throat, with white patches. I believe I have tonsillitis. 
I have just tried gargling salt water, which resulted in me vomiting for five minutes. Is there any other ways to cure this? 
I have googled and it says tonsillitis is a harm to the baby. Does anyone know if this is true? Help would be greatly appreciated! 
As id be looking at a lot of money to fly home today, and I'm meant to fly home in four days anyway. 
Thank you
