I had an ultrasound Monday and there is free fluid behind my uterus. My RE didn't seem too concerned about that but I have unexplained cramps as well. Also, sharp pain that comes and goes on the side I ovulated from. Saw a pregnancy in the uterus but that's all the info I have. Trying to calm myself with her lack of concern but it's not working! Anybody ever heard of this? I am 4w6d today.
