Hi Bonitachica, While I got my period right back after coming off the pill (after being on for 15 years), I will say my body remained screwed up for a long time (ovarian cysts and all kinds of other problems). Still not sure it’s 100% recovered, 3 years later. A number of my friends have taken months and months to get a period post-pill. Being on it for 4 years isn’t likely to be as problematic as 10+, but I would not underestimate the issues it can cause. Have you seen a real endocrinologist?
I doubt it’s your weight that’s the problem, if you had the same weight with no issues pre-pill. However, if you were low-carb for awhile, that can cause a lot of metabolic issues that take time to heal.
How many carbs are you eating now? Sounds like you may be eating a very fat-heavy diet, WAPF-style. Make sure you are eating plenty of carbs. A well-balanced diet is really best – square meals. Even if you have a gluten problem, you should be fine with white rice and white potatoes. Make sure you’re listing to what your body wants to eat, not what you think you “should” be eating. No need to eat processed junk, in my opinion, but including some refined foods like white rice can be helpful. Eat to hunger, not past it.
Also, make sure you are getting plenty of sleep/relaxation.
