7 weeks pregnant today

Starting Dec 2 I have been really sick, Saturday I couldn't even move off the couch. Today I couldn't get home fast enough to puke after filling my gas tank. The nausea has deffintally has kicked in. Today was the first time I puked and I have to say I feel so much better. Monday I got to see the baby again, I had a ultrasound done because I had a spotting of red blood on Sunday and I called the doctor and they had me come in, instead of Wed. everything is fine, the baby grew and it had a good heartbeat. I was relieved. My jeans are snug I have gained 5 lbs already OMG not good. It doesnt help that the progosterone makes you retain water. I want to excersise but either Im too tired or sick hopefully I can the second trimester lol.
