Needing advice

Me and my husband have been trying since August after I had a miscarriage. I went to the OBGYN two weeks ago and she said my ovaries look great. She looked at my tracking of my periods and how regular they are and she said that was where they needed to be. I went and did a progesterone blood test to see if I ovulated last month , my level was a 3.2 and she said that meant I ovulated and I was good. So to keep taking my vitamins and using ovulation test. My thing is I don’t really know what days I should be actually having sex. I have taking my prenatals, Maca Powder Vitamins, & Baby and Me 2 vitamins. Any help on what I can do ?
