Your thoughts please doc!!!
Good to have you back doc.

I'm really confused & maybe you can give me your thoughts. I posted a couple of weeks ago that I had been for a 'mid-cycle' check up at the gynae after being on Clomid 50mg cycle days 5 to 9. The doc saw a cyst on my right ovary & said my lining was thick but was perfectly normal in the 2nd half of a cycle (this was day 17). Up until then though I hadn't had a positive OPK at all & stopped testing. On day 18, I had a sharp pain in my left side that lasted for about 30 seconds & then it was gone. I assumed this was an ovulation pain. A couple of days later I developed thrush & a yellowy, cottage cheese type discharge that lasted for over a week. It was only itchy on & off & disappeared on its own. If I did indeed ovulate on day 18 then AF should have arrived yesterday but as yet there is nothing. My breasts have been very tender for over a week now which led me to believe that I am pregnant however, 2 HPT's have been negative & I had a qualitative blood test done this morning at Lancet that was negative - it looked like an HPT. I am now confused as to why AF hasn't arrived if I am not pregnant. I am on day 34 of my cycle & don't just want to rush off to the doctor to be told to wait 2 weeks & test again or go back after that time. Any thoughts or input you may have would be greatly appreciated.

Dear SLC

It is a very real possibility that you may have ovulated later than expected and it is not unusual for patients on clomid to sometimes ovulate around about day 18 or 19 of their cycle. It is equally possible to have a delayed menstrual cycle following clomid usage as a result of the persistence of the corpus luteum which is a normal occurence following ovulation. As there may have been more than one follicle ovulating, there would also be more than one corpus luteum luteal cyst being produced. This will result in an unusually elevated serum progesterone level which will result in a thickened persitent endometrial lining and this will then delay the onset of menses. However in the absence of a pregnancy the progesterone levels will eventually subside and this will result in a menstrual bleed or be it a fairly heavy flow. Should you not see your period by day 40 then I would suggest an ultra sound scan to exclude a persistent corpus luteum cyst which may need to be managed by hormonal means.
