Sour bears, Sour dough and weird cravings!

I know I've been bad about updating but I have a good excuse: I feel sick! From the moment I wake up until I go to sleep. And even at night I don't get a break! I wake up around 3AM hungry, thirsty, nauseous and I can't go back to sleep. I start the day without any energy and finish with none. So here are some updates:
on 7w2d I had pink discharge when I wiped. Of course I freaked out and had to call the Dr. Since it was a Saturday another Dr. was on call. I have seen him before for an IUI so I was comfortable. He said nothing to worry about, rest, drink and take it easy and if I am still worried call the next morning and he'll see me. Of course I did and went in for an US. Everything was fine! I was relieved to see that the baby is fine. My next US with my Dr. is going to be the last one at the fertility clinic and will be on Wednesday. I already have an apt with a high risk OB for my 10 weeks US!
So now let's go back to the post's title-I crave weird things! the other day it was sour dough bread that I got on the way home from dropping off Leah at school. I ate half a loaf. Yesterday I craved baked beans and ate a whole can. Today I am munching on sour bears. My tongue is so bruised from sucking on these things but oh they taste so good! I am feeling hangover, useless, energy less and sometimes I need to catch my breath. I feel like my body has been taken over by an alien. Can't do much these days and it sucks! I really hope the second trimester was here already.
