9th week has been a beast

I'm 9w 5d, and I'm struggling. I was so happy at the first of the week because my nausea had nearly disappeared, and I could eat. However, I've exchanged nausea and MS for extreme exhaustion and mild cramping. It's my first baby, and I have three days until my 2nd dr's visit (my LMP did not match with my baby's size, so they changed my due date, so I had a super early U/S) so I'm trying to hold out. I wake up sleepy and can hardly move all day. Then, I started having pulling sensations in my lower abdomen. I'm worried, and I feel bad. Anyone in the same boat?
