Haven't had sex at all...

TTC #1 for 6 months. This week is my fertile week. today I took opk and I'm ovualting. Since we been so stressed with having sex during fertile I didn't even bring sex up at all. I was saving it for this weekend. While tonight we are going out and won't be home till very late. Plus DH gets off of work at 4:00 and that's when we are leaving. So since we won't be home late I tried to have sex this morning but he turned me down because he has to get to work early. I just broke down and cried because we haven't had sex all week not since Sunday. Now we won't have sex till late tonight when I'm ovualting today. I just don't know how much I can take....whoever said getting pregnant was easy is a lair!
