Question?

Okay so I recently started using pregmate pregnancy tests do these test give false positive or negative cause I've taken 12 of them on several days to track and see if I conceived. Only 4 came out fait positive I'm highly confused ASF rn

The clear blue tests came up as clear as day positive at 5-7dpo I can't exactly remember when I took those but I'm currently 10 Dpo my afo comes in 4 days but boy I've been cramping off and on as well feeling a little flutters directly in my uterus. I've had 3 kids and multiple miscarriages for the past 4 yrs I started hormonal therapy 3 months ago. A few days ago I was relaxing and I thought I had to burp while I was eating nopeee it was so not a burp at all I havet dealt with that since 2016
