I'm sorry to hear AF turned up. It's very easy to feel deflated each time it occurs, but I'm sure you'll get a BFP soon if you keep trying. I read that it takes a 'normal' healthy couple an average of 6 months to fall pregnant when DTD at the right time, so keep trying! It's totally worth it. That being said, feel free to be upset too. It's heartbreaking each month it doesn't work.
