I know it is hard ladies, but it WILL happen. I had an absolute meltdown in June after over two years trying. £6K failed IVF, 9 rounds of fertility drugs and DTD on demand for weeks on end every cycle. I had pretty much given up and just collapsed into sobs on hubby saying I was done, had enough of it all, we have only one child and that is how it is going to be. I was also sick of pregnancy announcements and avoided friends who were pregnant or who had babies and just wanted to know when it would be my turn. Lo and behold, it turns out I was actually just pregnant when I had my meltdown. It took me time to get the right combination of everything - two medications to work together to finally regulate me, DTD at the right time, hubby's sperm count/motility slightly improved by vitamins etc I wished I was one of those ladies that fell PG instantly but unfortunately it took years of investigations and different medications and a bit of self-diagnosis and stamping my feet at the docs.
Try not to get too down, ladies. Big hug xx
