My partner and I have had a full fertility check from two different doctors actually and there is no reason as to why we have not fallen pregnant again. We are both in healthy working order and that is what is frustrating us the most. Thanks for your response though
You need to see a doctor. If you've been trying for that long with no success you need to see a doctor about it and they can look into anything that might be causing it. As for the irregular periods all of a sudden, it could be a number of things but you need to be examined to determine what it is.
