First time using ovulation tests. The first day I tried, the test line was lighter than the control line. So I tested everyday for a few days. On October 11, the test line was extremely dark, darker than the control line. I tested again the next day to see what showed up and the test line got lighter, so I did ovulate on October 11.  What are the chances of conceiving with a positive ovulation test? Given you have sex prior to ovulation and afterwards as well. I believe I'm on day 7 of my two week wait and it's driving me crazy already lol.
