#asktheexperts Hi Doctor, my last periods was on 6th jul & from the 2nd day of cycle started to take leteoz tab for 5days (till 11th jul). and had taken ovitrelle 250mg injection on 10th day of cycle (15th jul). and from 13th day of cycle (18th jul) started zydrogestrone tab for 18days (till 4th aug). all the medications are taken as per doctors prescription. and on 31st day of cycle (aug 5th) took both urine hcg test at home & beta hcg blood test. both tests are negative. and doctor advised to stop zydrogestrone tab. and till now I didn't get my periods but I'm having a very strong nauseous feeling from past 2days. what shall I do??
