Did anyone have weird LH surges?

I keep getting random results on my okps. I got positives around 12 dpo and again at like 20 dpo but they will be there one test and not later in the day. or I will get an almost positive and then nothing there. I have been testing multiple times a day up to 4x a day but it is so weird... I'm not sure if they are because I'm still breastfeeding or because I'm using the cheapie tests and they aren't reading right or if I'm not ovulating. I also have endometriosis and ovarian cysts so idk if that could be related??? so confused... 🤷
