Talk to Gynecologist on What To Expect After Ecp?

On 13th day of my cycle, we had unprotected ic only once but my husband pulled out early. We are not planning a baby so I took 0.75mg greenstar ecp (both pills at the same time) on 4th day of ic after my gynaecologist recommended it.

Now what should I expect? 1- 3-days bleeding after 1 day of taking pills (as my doc said)? Periods cramps? 2- Spotting till periods naturally occur? 3- Proper periods according to my cycle? 4- After proper periods, is it confirmed that I'm not pregnant and the pre cums (if any) didn't meet the egg? Or should I take pregnancy at home test? 5- What are the other things that will happen to my body due to ecp? (Kindly be clear with this one, especially mention all the harmonal issues) 6- If I notice any hormonal issues will they disappear soon or will they be permanent? If yes then how long will it take?

Kindly be specific with the answers.
