Hcg and feeling concerned...

Melissa
Hcg is so variable for each pregnancy so I know that much. But today I called my midwife cause I'm not feeling my "normal" crampy, sore, pukey that I have with all my babies.. I was worried. She checked my hcg and I'm sitting at just over 123k, will retest in 48 hours. What I thought tho was that once you reach a certain point, hcg is no longer a reliable way to monitor a pregnancy. I thought that number was high for 8+6 weeks.. Anyone have any insight? I'm laying here now with a crampy sore belly, so that's encouraging.
