Hmm, help after finishing pill etc

Jessica • Pregnant with no 2 💓
I finished my last pill on the 15/. I started my period on the 18/4 finished my period on 22/4. Bd on 23/4 24/4. And I've got a lot of cramping pains today. Any ideas ladies? I know you can sometimes have a period after finishing your pills but I'm confused! I've got endo and trying my best to conceive as soon as possible 😁.
