ovary ache pain after stopping birth control???

Alicia

so I was on Nuva ring for years then decided to switch to pill to help with acne, but I let myself have normal period cycle then started taking the pill after that week long period but I only took the pills for a week and half but kept skipping after that so we decided since I'm 27 and we both want a baby why not just try so I didn't take pill and had another dull 5 day period shortly later actually and had sex then also had sex 2 days in a row after that period ended and now I started experiencing ovary achey type pain but it's not bad or anything just weird what is that does anyone know??? I'm also slightly randomly nauseas feeling is it possible to be early prego symptoms or just in my head??
