Progesterone Nightmare

Ok ladies. I'm just here to vent. I'm 10.5 weeks and have been on progesterone since week 4. I'm so tired of going to get blood work done weekly. My poor veins are bruised and I look like some drug addict. What's worse is 1 week my levels are an amazing 64.4, then the next it's at 34, then back up to 50, then down to 29. I realize it's completely normal to fluctuate, but it doesn't make the scare and worry any easier. I'm ready for this beginning phase to be over. I want to enjoy my pregnancy so much, but all I do is count the days to get my next blood result to reassure myself that baby is ok.
