Hello, I would be happy to help you with your question.

It sounds as though you have a solid handle on your cycles. I am assuming that you are doing some form of ovulation detection as well. The progesterone supplementation that you are taking during the second half of your cycle is most certainly 'extending' that half of your cycle and certainly could lead to a slight delay in when you get your period. So, when you state that you are 2 days late, it sounds normal at this point given the progesterone supplementation.

As far as IF you are pregnant, it is also possible that the test has not turned positive at this point. In most cases I would expect it to have turned positive by now, but not in all cases.

I would not give up hope if you are not pregnant with this cycle. If your partner has not done a semen analysis, this should be done as well (I find that this is often forgotten).

I hope that this helps - please ask if you have followup questions!

In cases of women whom we give progesterone to to induce a period who did NOT ovulate, once they finish the course of progesterone, it is not unusual to take 3-5 days before they notice the start of a period. So in your case, it might be anywhere from 3-5 days (perhaps even up to 7 days) after discontinuing the progesterone.

I would repeat the pregnancy test about one week after when you last checked. At that point, if it is negative, then you are not pregnant.

I hope that this answers all of your questions - let me know!
