Getting your period after getting cummed in?

(I originally posted this in the sexplanations thread realizing it belongs here)

Hi, ladies!

So I find this rather odd. I notice sometimes after my fiancé cums in me I begin my period a few days later. I noticed I started to spot yesterday and this morning. I’m very irregular, in fact I haven’t had my period since September 21st. Obviously I’m not pregnant, never have been.

We’re also not exactly trying to conceive either.

I haven’t taken birth control in almost 10 years. (I’m 31 years old if you’re wondering and have been irregular since I started menstruating) My girlfriends always ask if I’m ever scared or concerned of being pregnant since I go months without aunt flow coming to visit. I’m honestly so used to it by now that I barely worry about it.

But back to the subject!

Has anyone else tend to get their period after your guy cums in you too?

**UPDATE**

In this post on the previous thread someone mentioned that cum softens the cervix. That definitely was a shock to me! I never heard that before, but when searching it up it looks like it’s true.
