It's been almost 2 years now!

Hi, I'm 26 years old and have been with my partner for 9 years. We started TTC in January 2015. I fell pregnant in July 2015 but lost it very quickly early on. We've been trying ever since and it's almost 2 years since we had a miscarriage and nothing. We try to have sex when we spot the egg white cm but it all feels a little hopeless. We've recently bought a house together so timing is perfect for it to happen for us. Just starting to feel a little desperate, especially when some of my friends didnt even have to try and they're pregnant, one of them has had 2 accidental pregnancies and theres me trying so hard over here!
