My first sign was period like cramping a few days before I was due my period, and was actually telling my fiance that day I didnt think I was pregnant that month, when a week later a postive test. It is possible to still get your period, however the pains could just be because of the constipation, your system backing up do you have any other symptoms? Are you TTC because its quite easy to imagine you've got more symptoms than you have trust me been there and done that!
