? about using progesterone while TTC and return of cycle

[railyuh]

For those of you that have used progesterone while TTC, how long did it take for your cycle to return when you didn't get pregnant?

If it matters, I was taking 100mg of prometrium as a suppository twice a day. My last dose was Friday evening and I have had negative tests through today (15dpo).

This was my first cycle using the progesterone and I am just wondering what "normal" is for the return of AF before I call my RE over nothing. I had kind of assumed AF would just show up right away, like the next day or so and it hasn't. I just want to get this over with so we can move on to the next cycle.

Progesterone suppositories will lengthen your cycle. If you have a bfn at day 14 post ovulation, most docs say stop taking it. Just to be safe, call your re and tell them. also, get a plan for next cycle so you aren't stuck in no flo land with no bfp!
