I'm measuring a little small too...thought I was 8 weeks and only measured 7+2 (I know my dates are right). But the heartbeat was strong and my doctor isnt worried. I think there can be a lot of discrepancy in size this early, especially because they are so small and hard to measure. Keep your head up and try not to worry too much.
As for me, tired, cranky, morning sickness, headache, sore bbs=miserable. I know they're good symptoms and I'm thankful for them but sheesh I am worn down! Also have to get my thyroid tested for the third time on Thursday. It has been high and I might need to go on meds but my second result was better than the first so she is holding off on meds until after the next test. Just overwhelming as I feel I have enough on my mind with the cerclage and progesterone injections I just don't want to deal with anything else!
