So about 10 mins ago I just suddenly had quite bad D... I'm very stressed at the moment. A few assignments due this week for uni, broke up with partner, moving house... is it possible these can just set it off like this? My period did also start yesterday, early... probably due to the stress.I'm very worried it's for another reason, but I can't see what would just do that? I've had my IBS reasonably under control recently...
