Beta #3 today = 515. That's up from 175 on Monday. They want me to come in on Friday to get my levels again and then I will be scheduled for an early u/s next Wednesday or Friday. By my calculations, I am 4w4d today. At this point, everything looks good on paper, but I'm still very apprehensive given my past losses. I am continuing with the progesterone suppositories and baby aspirin, but the RE isn't convinced that I need heparin or lovenox yet - that's according to the nurse anyway. She didn't call me with today's results until almost the end of the day and I didn't ask to speak with the RE. I think I am going to call tomorrow and ask to speak directly with him to find out what he is thinking and why. On one hand, I don't want to do anything unnecessary, but on the other hand I think I would regret not trying something different this time if this pregnancy ends like my others. I wish there was some magical way that I could look inside my uterus and see what is going on down there. You know, like some sort of 24 hour video surveillance I could check in on whenever I felt like it just to reassure myself that everything is progressing as it should be. Maybe I could try to invest in my own personal vag cam! Wouldn't that be something? Still hoping that this little one decides to stick around.
