Sorry to break it to you, but it’s not just Mercury that goes into retrograde, so does your period.
By now you’ll be aware that we basically know nothing about our reproductive organs (thanks sex education) and it turns out that the same applies to our periods.
Before this news fills you with terror – retrograde menstruation (as this process is known) is super common, with 90% of us who have periods experiencing it.
However, it can be painful if there is a lot of blood lining the cavity as blood is an irritant, as Dr Rajan points out.
If you have a condition where your cervical opening is narrower than average, you’re also more likely to experience retrograde menstruation.
He also stresses that if you have any excessive pain and excessive bleeding it’s super important that you go and speak to your doctor.
