I recently started taking lo loestrin fe. Before I was on this I was on nuvaring. I took the ring out and about a week later started lo loestrin. I can't remember if I got my period within that week but I did get it about halfway through my birth control pack. It was not light at all it was like an actual period. Now I'm about a week away from being done with my second birth control pack and still haven't gotten a period. I don't understand. Is this normal when first changing birth control? I also have been feeling a little crampy lately but no period.
