My periods are so regular you can set your watch by them, they even turn up at the same time of day! I EBF my DS, and periods returned 6w PP. I've been through periods of depression and stress and illness and nothing has ever affected my period, not that I'm ill or stressed at the moment anyway.
The only time my period was late I did a test the next day and it was positive, and I was pregnant with DS. I have a 25 day cycle and am today on day 28... I did a test on day 26 (the other one in the pack of two from DS! Close to the expiry date but still in date) and it was negative. Woke up feeling sick this morning (had morning sickness with DS from 4 weeks) and was genuinely shocked to get another negative result?
I know you can get negative results and still be pregnant, I guess as I have a shorter cycle that may make a difference (if I were the average person, my period would only be due today)? I'll test again in a few days, but if I'm not pregnant, what the hell is going on!? And if I am, my HCG levels are clearly lower than last time, could this be a sign that I'm going to miscarry or something? [paranoid]
