I feel so sick

I'm 4w 3d. And the nausea kicked in this afternoon. I had a couple of very mild episodes before now and I thought "how exciting" but now, i want to crawl into bed and cry a little bit. I normally power through illness, but is this really what it's going to be like for the next two months? Is it generally constant or can you have good days? Any anti nausea remedies much appreciated x
