My last period started on 09/01/12 and lasted only 3 days. My next period was due 13/02/12 and 6 days beforehand I started bleeding lightly which lasted a day. I missed that period snd was starting to get pretty excited. Today, 05/03/12, is exactly 3 weeks since my period should have started. Yesterday I had a few mild. cramps with tiny amojnt of brown discharge and today I have a very light flow which doesn't even fill up a pad. I would also be ovulating today. I have done 4 upts, all negative and I'm very confused as I have been feeling nauseous with HUGE, extremely sore breats, mild cramping and always exhausted. I really thought I was pregnant this time. Was going to make drs appt this week but I'm not sure if there is any point now. Pls help!
