Hi,I just recently started my period after being 5 days late, (this happens occasionally, but every time the pregnancy test comes back negative) and when this happens I usually have terrible cramps, that nothing seems to help, my lower abdomen feels like it's spasming, and it's very hard to even walk. I have been told in the past that I have ovarian cysts, does this have anything to do with that? Appreciate any answers at this point
