Right that's it I give up!

Took me 5 years to get pregnant with my gorgeous son! Who I am over the moon to have an couldn't be any happier to have him. But I want other! It's been 2 years now and I just can't take the stress anymore we have tried everything you can think of! Every month I get overwhelmed with disappointment and I feel it's taking me away from being a good mum. Everyone says ooo be careful you get pregnant right after the 1st. Bullshit we started having sex again 5 weeks after giving birth and have never used protection.
