Try to relax. You will have had cramping because the catheter went into your cervix, which didn't appreciate being messed with. Also, the progesterone you are doubtless taking will give cramps. Stay off your feet, stay hopeful. Nothing about cramping (either present or absent) means the procedure was successful or the opposite.
Thank you for replying!!!! THis is a very stressful time and I keep running all types of scenarios in my head, and I have watched so many youtube videos that I think I need to ask my husband to take the computer away from me. I'm trying to keep positive!
