Here's what's happening my cycles are 28-32 days and basically started spotting ON cd30 which never happens to me never got any heavier no cramps no bloating no backache nothing i was sick literally straight away after eating egg on toast and coffee the other day nothing after that. I just don't know what to do i have other strip tests so do i wait a few days til i test again I've looked online and says spotting before af don't count and i can't let glow know if i have started af
