I know, I know... it's probably a dumb question.  I'm on estrogen and progesterone right now... on the second week of my 2ww aftter IVF.  I've felt fleeting cramps a couple of times, but right now I feel more AF-ish cramps than before.  Just wondering if I can be hopeful... ?  Cause I mean, I shouldn't be getting AF on these meds right?  
Sorry, I haven't been posting as much lately... work has got me hoppin' and DH and I had a jam packed weekend!!!
Hope you're each doing well as you can be!

Re: If your on Estrace & Prog, you shouldn't get AF , right?
You can get your period when on those medications.
The only time I have not bleed through progesterone is when I am pregnant.
ETA: However, progesterone is known to delay a lot of women's periods.
I agree that you can get your period on those meds.
I got mine on Saturday after a negative Pg test on Friday.
Everyone is different though...stay hopeful and positive.
I thought AF would be delayed for awhile but I was happy that it come on Saturday so that I could quickly start #2.
I am someone who did get my period on these medications. It sucks and can happen
I am another one that this happened to. Not fun.
I can only speak about estrace - as I haven't done prog - but I did get AF while on estrogen following my IUI.
