Hi.. I am 29 years 10 months old married from past nine months.. Had a history of irregular menstrual cycle since its start in teens.. Detected of thyroid in may which was not there earlier. Visited a senior gynaecologist who advised me to go on fertility drugs for conception and prescribed me with fertomid 100 mg from day 2 to day 6 and duphaston 10 mg from day 16 for 12 days along with thyroxine 25 mcg. I started the course in mid June and since then my periods have been exact 30 days.. I just finished my third month of the course and my period is delayed by seven days now.. It should have started on 13th September and today is 19th.. In the third month I took duphaston after breakfast than previous two times which I took after dinner.. I took a hpt on 15th which was negative and repeated it on 19th which showed a faint line in test window.. Have sore nipples for more than 20 days now.. And slight on and off cramps in mid stomach near naval also now feel some fluttering towards left side of abdomen .. Am I pregnant .. Is it possible to miss periods this long with fertomid if not pregnant.. Plz help
