Trying to conceive

Charlotte

Me and my partner have been trying to conceive for just over a year now, nothing has happened.

However in the last 4 months my periods have become so irregular, up until then my periods start on the 1st of each month without fail, the last 3 months have been up to 1 week late, whereas January I have no period at all. Anybody got any advice as to what could be going on? Pregnancy test is coming up negative.
