I just came back from my hsg. I must say I didnt sleep for 2 days, I couldnt eat for 2 days. I was so scared last night I cried to sleep. But I was ready for the pain, I want this baby so much I was ready. Got to the hospital, my doc was waiting for me inside. I DIDNT FEEL ANYTHING! I had so much worst menstrual cramps than that! so crazy! I couldnt stop laughing after the test. my uterus and fallopian tubes were beautiful! no obstruction, nothing! I requested a copy of the pictures He told me to ttc this month and he said its likely i could be pregnant in a couple of days! If you have this schedule, dont be scared! its worth the relieve!
