Well I'm not sure if that would have anything to do with it or not but it could just be an irregular period but if you do not start your period next month I would see you doctor. Hope this helps!
I believe there should be as I am going through the same thing, I am taking about 9 supplements, and right now I am on CD 43 and AF is not visiting. I do not have my supplements in front of me to give proper dosage, but here is what I am taking. Selenium, green Tea, Omega 3 Fish oil, Folbee plus, Vitamin C, Serulina, MSM, every now and again I add vitamin b6 and B50. I am sexual active but not that much. It will be nice if I am pregnant but I do not feel pregnant at all, and have no symptoms. I am a lilttle scared that maybe I am coming with something other than pregnancy.
