fish oil and o...

so this month I've been taking fish oil, and for a couple days plain mucinex. I've been having my normal csection scar pain that happens around o, but today was odd. the pain got a lot heavier, and I had stabbing pains in my ovary. I started thinking I had a cyst rupture, but it never got worse and has waned. the one time I had a ruptured cyst I was in the hospital. so my question is does anyone know if either of those pills could have made o more painful? I've also felt fatigued since.
