Hemorrhoids! Help!

I never had hemorrhoids so far in the pregnancy or if I did feel it coming up, it would go away on its own overnight. I'm now 35 weeks and I've had 3 appear around my butthole in the last 2 days.
I'm not constipated and have regular bowel movements, nothing strained. What can I do?! It's so painful that I can't sit or turn over on the bed. 
I went to urgent care last night and they prescribed me Proctofoam which is a steroid but after two applications, still no improvement. This is so unbearable! I didn't think my last few weeks would be spent in bed because my butt felt like it was being cut by razors.
