Maca Powder

Has anyone used maca powder while TTC? I got a BFP and am now 5 weeks and have cut it down to one 500mg capsule a day since finding out but don’t know if I should ween off of it or what. The doctors office obviously said I shouldn’t need to take it just because there are no studies done on this so they can’t know for sure. But I have seen things online where women safely take it throughout pregnancy. I’m kind of scared to cut it off cold turkey it case it is helping with things still at this point. Has anyone had any experience with this while pregnant?
