Light at the end of the tunnel

This will be our first baby and I have run the gambit on symptoms, common and uncommon, since before missing my period (started with extreme fatigue). I've been nauseous this whole time and puked constantly for about a week or so. then suddenly, I feel better. I haven't thrown up since Saturday, didn't feel well Sunday but made it through and yesterday I felt largely fine. This morning once again zero nausea. I'm a bit too nervous to tempt fate and do too much (gods I HATE throwing up) but I'm hoping this is the beginning of the end of the digestive upset. I'm constipated but that I can handle. I'm 8w1d today. I don't have my first ultrasound until the 30th but I'm trying not to be too crazy about it!
