Id say this is definitely your positive!
Its hard to know what pain is what, in 2012 I had surgery well two actually, one was to remove my gallbladder the second was to repair the bad job they did which caused my ahernia, and wasnt found out for a week later despite me telling them I couldn't go to the loo and being sick none stop for a week! But since then I get bad pains every time my cycle does anything that causes me to bloat I think id pushes on scar tissue, im not sure, thats why I asked because its hard to know whats normal, what's from pcos or my surgeries. sometimes I wish I could see what was happening inside my body!
