Help!!!! Need advice from some ladies

Do today I woke up and took a CBD ovulation test and received a "high" reading again, the 4th day in a row. I've also used other tests and they seem to be negative but the lines are never a clear answer. My question is for anyone who has struggled with these same issues, i mean a high reading is great but 4 days of it seems like alot, and it seems like every time I've tested with these testers, ive recorded this reading... the only day I didnt get a positive reading was this last Thursday, it was late afternoon and i took my first ever CBD test and it was an empty circle, that was of course discouraging, but the next morning the test showed a high result... i guess I just need some reassurance. Any other ladies have alot of "high" days? How many? Are the tests accurate or should I be using another test too??

Help....
