Sharp hip pain during period

This is new to me. I woke up with a sharp pain on the left side of my hip. It feels like someone hit me in the bone with a hammer. It’s not excruciating but noticeable and because I’m an over thinker, I am going to take ibuprofen. I’m on day 2 of my period and 14 months PP. Google says endometriosis so I’m freaked out! Anyone know what causes this or relate? Thanks!
