DH and I are very lucky to have a DD. We always wanted 2 but for various reasons we've waited until DD is 2, although wanted to do it sooner. She was conceived very quickly in the first month of trying. We (naively) thought it would be like that this time. It's only been 4 months which isn't a long time I know but every period that comes is more upsetting. At what point do I go to my GP? I'm mid thirties and DH is early forties so I know time isn't really on our side. DH keeps making excuses like "we've not been trying hard enough" or "we're both a bit run down". I feel a bit worried that it won't happen for us. When is there officially a problem worth getting a GP opinion for?
