Do I need to have a positive ovulation test to get my HCG shot? I’m suppose to do it tonight. With IUI 12 hours and 36 hours after trigger shot. Did an ultrasound this morning with 2 follicles on the left at 20 and 18. And 2 follicles on the right at 16 and 13. Lining is 7.11. But just now I took my Clearblue advance test and came back Negative. Is this still ok?
