Any ideas??

So I am 30 years old and am 9 months post partum, I stopped pumping at around 7 weeks. My first pp period came at about 8 weeks and since then periods have been regular. Now this is happening.🤔 My period came 5 days early in early May, and it came again later in May a whopping 11 days early. Idk if it's a coincidence or a correlation, but both periods in May started within 12 hours of sexual intercourse 🧐

I'm curious if anything has happened like this to other ladies?🤷‍♀️ This is not typical for me as my periods (other than a random few times in the past 17 years) have always been on time and regular.
