I was given ova shield ds combipack for induction of ovulation. However, follicle growth was very slow and on 18th day it reached 19 mm and doctor gave 5000 iu of hcg on day 19th. On 21st day when ultrasound was done, follicle had not ruptured still and doctor has given 2.5 mg later (2 doses) and suggested tvs on 23rd day again. I am not sure what is happening. We did have intercourse before and after hcg shot. Is there a possibility of conceiving and can first clomid (50 mg for 5 days for induction) and now letro can be given?
