What do you girls think? Positive or evap line?

Sandra

Hi girls! I am 18DPO and supposed to get my period tomorrow (I ovulated early this cycle confirmed by clearblue advanced ovulation tests). I took A LOT of expensive pregnancy tests and they were all negative, so I continued testing with the cheap easy at home tests from Amazon and I got this line!

I read reviews that these tests get a lot of evap lines and fake positives. Also, I would of thought the line to be darker if I am actually pregnant and 18DPO. Let me know if you experienced anything like that and what do you think!!
