Progesterone 2.850 ng/ml

Hi there I check my progesterone level and I found out that was low, we are trying since last year on August . My husband has low motility too (32%) The thing is that the month that I checked my progesterone I don’t think I ovulate ( I always feel cramps when I have ovulation) that month I didn’t felt cramps like I usually do and I had late periods too,but am sure that other months I ovulated and everything else is ok with me like tsh , multi hormonal, ultrasound. The only thing that I didn’t check was progesterone until know ,my doctor says that was necessary because everything else was ok and the cause that I couldn’t get pregnant was my husband motility.So I ask her I want to check my progesterone I did and was 2.850 she said is low and I have to go to fertility doctor , but I insisted to recheck it again because am sure that month I didn’t ovulate . Anyone had the same thing? What can I do to increase my progesterone, I bought vitamins B6 and E
