When would you suggest a visit to the gp? My usual periods vary between 5 and 6 weeks apart. Its now been 7 weeks and a day and still no sign. Im exhausted all the time, and hungrier than usual but still getting negative tests. I've been to the gp about my periods being funny a few times as recently they've just been brown and light (sorry for tmi) so don't wanna go again too soon x hope that makes sense
