Confused

hazel

So I got an Positive LH Peak in the 28- 30 of January on the 31 of course it was negative. The whole time I was thinking I ovulated on the 28 or 29 now I'm thinking I ovulated on the 30th because I got a negative ovulation test on the 31. I also experiencing tender sensitivity of my boobs and nipples and slight cramps. I'm so out of wack I'm not sure what DPO I'm on. HELP! 🙄
