So my period cycle is 4 weeks apart then 6 weeks apart in that pattern. this period cycle is suppose to be 6 weeks but it has been just over 9 weeks now. My partner and I have had unprotected sex 3 times since the 3rd week mark to the 6th week mark and because I am not sure when I ovulate and am fertile during my 6 week cycle I don't know weather or not I am pregnant or something else is wrong. I could be anywhere from 6 weeks pregnant to 3 weeks and at 3 weeks pregnancy tests won't pick it up. Any advice would be much appreciated. :)
