My periods have always been fairly regular. 28-30 days except for after ivf treatments and fibroid operations when the went a bit all over the place. Thankfully they always went back to normal in the end.
When I was a teenager I had really bad flu, so I ended up missing my period that month. My body therefore decided that I needed two periods the following month. My body is kind like that.
So after getting pregnant and miscarrying I went 11 weeks between periods (not including the miscarriage bleed in between). So lucky old me, I’m having two periods this month. You’d think my body would give me a break. Just hope it goes back to once a month after this.
