I have a question ???

I miscarried sometime in January and I found on the 31st , I would have been 20 weeks but my baby girl stopped growing at 17 weeks. I had my D&E on February 4 , I bleed for two weeks and my doctor gave me the okay to do whatever, but he said wait at least one cycle ttc again soo fast forward I had my first cycle on March 25 . My question how long did it take to conceive right after your period
