Hey everyone, I have a question about PIO injections. I've had 3 FET's and have always used Crinone and PVS. This round I didn't want to use those so I started PIO 9 days ago and I had my FET 4 days ago. Ever since the night of transfer I've had mild lower abdominal cramping and lower back pain off and on. I didn't have those symptoms the few days I was on PIO before transfer. I'm trying not to symptom spot, but what do you think?
