coming up on month 11

Coming up on month 11 of TTC and I just got AF today πŸ˜₯ I'm so frustrated and now I'm starting to get worried. My OBGYN told me I'm completely healthy I should have no problem getting pregnant, my spouse has been checked he's good to go... we have sex all the time so it's hard to think I'm missing the right day. I don't even know what to do anymore I'm beyond frustrated I'm beginning to feel broken. We want a baby so bad, I really swore this was the month. πŸ˜₯πŸ˜₯
