I feel like I made a mistake. I been taken a ovulation test everyday since cd9. On cd14 I had a almost positive and ran out of test. I went to try to get more but they didn't have any at the store so I said forget it because my husband was out of town working and couldn't bed anyways. But now I feel bad and feel like I should have went to another store to get some to see exactly when my surge was.. I know I can't change it but I hate wondering when cause it could have been that dark for a another day or so. Dang it!!!
