Waiting for period to start meds for FET...............

This will be my second time! First time worked and have a healthy 2yr old! I don’t kno why but I feel more nervous This time around than last time! Feel like I won’t be so lucky! I wish I could get some positive thoughts but I just can’t seem to shake the worry and I’m already dreading that tww! Anyone else due to start! Estimated FET should be around 3/3/20
