Help with Opk! Please!!

Hey guys, can anyone take a look at these for me and let me know what they think? I just stopped BC pill 1/1/20 and I’m trying to get a feel for my cycle to start ttc. I know glow ovulation prediction is most likely wrong since I’m just getting off the pill and have no clue what my cycles are like, but it gave me an idea of to when to start testing. I had my withdrawal bleed 1/3-1/9. CD 15 pic is below which I thought was positive. I just took another test today CD 19(also pic below) which looks even darker! I did test in between these two days and they were lower. Do you think they’re both positive? Or was CD 15 just really close? I’m so confused and no idea what I’m doing so any advice would be helpful! Thank you!
