Hi there. Yep, this happens to lots of women. Something else besides pregnancy is most likely going on. A slow thyroid can cause this as can hormonal issues. I had both of these and got periods every 3 to 4 months for about a year and a half. Was NOT pregnant, it was these other things affecting my hormones, and thus, my cycle.
At the two month mark of no period, see a doctor to help determine why. good luck
Thank you, specialmom.
After my first born, my periods were all over the shop but lately they have been like clockwork. Until now.
Thank you again, you've been really helpful!
