Nervous Nelly!

Starting Progesterone tonight to force my body into having a period since I haven't had one since May.  I'm so nervous about it!  I have stupid health anxiety, and of course read the potential serious health problems.  It doesn't help I just quit smoking and am overweight, so more at risk. 
​Anyone take it before and not end up with blood clots, etc?  I need good vibes!  
​I keep telling myself it's only 10 days and then I'm onto the next step of my baby making progress!  (Aka clomid)
