Hi! From what I understand norethisterone is a type of birth control or progesterone given to sometimes jumpstart the shedding of your lining. Please make sure before you do anything else that you take a pregnancy test to make 100% sure you haven't conceived in the mean time.
It can take up to a week, sometimes a few more days than that, to get AF to start after that type of medicine. Once it does, you'll count your first full day of flow as CD1. It may be heavy or light, or unusual in other ways, but make sure you wait for the first full day of flow before starting the clomid.
Normal dosing days are CD 3-7 or 5-9. Taking it days 3-7 is said to encourage more follicles to develop, while taking it days 5-9 is more geared towards egg quality.
So you take the clomid, let's say days 3-7. You should start using OPKs around CD10 once a day to track ovulation. When I did clomid I started taking them twice a day around CD 12 to make sure I didn't miss my surge. You can ovulate anywhere between CD12-20 something. It's not an exact science.
The second you see egg quality cervical mucus you should start baby dancing, although a lot of people start DTD every other day starting on CD10 until ovulation is confirmed. I would do the latter if you are able to and your partner doesn't have any sperm issues.
Once you get a positive OPK you should ovulate within 24-36 hours. Other than charting or by ultrasound and bloodwork there's no way to tell for sure that you ovulated. This is where the 21 day blood test she gave you kicks in...
If you were to ovulate on or around day 14 of your cycle which is when most women normally ovulate, you would wait 7 days (meaning CD 21), to do your progesterone test. The best best BEST bet is to make sure you have ovulated and THEN wait 7 days before you do your day 21 progesterone test. It is a blood test that will tell you the level of progesterone in your body and either confirm or deny actual ovulation. I hope that makes sense.
If you are new to the idea of charting and this is your first cycle on Clomid, I HIGHLY recommend you get some OPKS and possibly chart your temps for this cycle. It will be so helpful in the future if you need the historical reference for a future cycle. It will also give you immense peace of mind to know when you ovulated and what signs your body gives you when you ovulate, establish a pattern of when you are ovulating on the clomid, and most importantly, if the dose you are taking is effective.
I am pretty sure you knew all of this already, but I figured I'd get as much info in here as I could in case someone else has any questions. I hope its helpful and I wish you all the best!
