Just started using ovulation strips On the 13 I had 2 lines but the test line was faint so I am assuming that it was negative on the 14th and today I had just one  another negative so my question is how can I detect my ovulation day because I know a lot of you ask what is your DPO and I don't know. According to Glow I was ovulating on the 12th. All this is confusing to me because with my first I didn't do all of this I got pregnant within 1 to 2 months but now TTC number two I have been for over a year and now I'm willing to try anything to help me know when try to concieve
