I am confused as to whether I've got a unusual period this month or had a very early miscarriage (chemical pregnancy)? I Ovulated and DTD 15 days ago (trying the O plus 12 method to try to sway for a girl). Today had very strong cramps (I don't usually get cramps this bad when I get my period), followed by heavy bright red blood, along with bad lower back pain. Haven't passed any clots at this stage. Now my period isn't due for another 3-4 days (as usually have a longer cycle, and my period never comes early if anything I get it later then when it's due). I haven't taken a pregnancy test as was going to wait until my period was due before taking one. Haven't really had any pregnancy symptoms prior to this, expect a little bit of breast tenderness, I have been charting my temp and it has been up, but this morning was back down a again. Am I overreacting? Has anyone else experienced anything similar?
