Hi, me & my husband are trying to conceive for 3 months, I was suppose to have my period on 27.07.2013 but on 23.07 I experienced painful cramps but just one big spot of blood and then it stopped, then the next day (24.07) I had bleeding ( but light in colour) with brown discharge too.. enough to fill one pad, and yesterday just a little bit ( light in colour).. normally my periods are quite different.. I feel bloated,constipated,have headaches, little nausea.. not sure if pregnant.. can someone please help me with this confusion ?
