Gone off the pill after 12 years. Weight gain and 2 months without period.

Hi friends, I have a question and I hope you can help me out. I have been on birth control pill for the last 12 years and recently went off of it in April. It is now June, and I still have not had a period. I have also gained a little weight and have had minor spotting but no period yet. Has this happened to anyone else who’s been on the birth control pill for long periods of time and once you started your period finally, did the bloating and weight gain start to diminish?
