I started taking Maca root a few weeks (3 Weeks I think) ago and got my first natural period after not having one for 5 months... it's now 2 weeks past when my period started and I've vomitted and my temperature elevated up to 37.40 degrees it's normally about 35 - 36 degrees, I've been sleeping heaps and feel really weird I also have lost my appetite! Now because I have pcos normally when I take an ovulation test it comes up with 2 lines (a faint line & a dark one)  but today it came up with just the dark one... Is it possible I ovulated early?? And am pregnant? Me & my SO have had sex a couple times since my period! Advice please!
