Stims Day 7

Today was my day 7 stims ultrasound and bloodwork. I had 3 follicles one at 19 one at 17 and one at 13 ... I am going tomorrow (stims day 8) for ultrasound and bloodwork ..I am not sure what my LH levels .. and I am taking 5 units Lupron which is supposed to stop ovulation. But with the 17 and 19 mm sized follicles I am worried I would have a premature ovulation and cycle gets canceled.

Anyone has any thoughts on this
