Having irregular cycles can make it challenging to conceive, but there are ways to improve your chances. One simple solution is to have regular sexual intercourse every two to three days. It's important to note that there isn't a daily medication that can regulate your cycle, aside from contraceptives which may not be helpful in your situation. If you have recently stopped taking birth control pills, it's normal for your cycle to be irregular for a few weeks or months before returning to normal. Just be patient and give it some time to regulate itself.
