Hello Doctor, I have a history of PCO's and have been under treatment since September 2009. I still have irregular periods. Currently on Glycomet and Blong F. Last period was on May 15th. June 15th spotting were found. Spotting again on 21st(increased) took Letoval for 10 days bleeding did not stop. On 9th July went for follicular study which showed endometrium thickness is 19mm. Doc has put me on Duphaston for 15 days. Can I conceive even though there are spottings? Why am I having spotting for such a long period?
