TTC with hormones

Kenedy

So my doctor prescribed me progesterone to induce my period and my fertile days after my period for this month are the 23-28th I believe somewhere I’m there. But anyways you’re suppose to take it the first 10 days of every month so does anybody have any advice on how I should do that ? I don’t wanna start trying to get pregnant and then take the hormone the week after cause I’m worried it’ll mess things up ... or will it not ? Help.
