The last one looks like it could be a faint positive but the other two don’t look like anything. I’d wait a couple days and test again
I know I need to wait for a bit, the Tesco tests don’t have very good reviews but have had a faint line on Asda ones too. Today’s test
You probably ovulated a little before then, if these are positive. Implantation can happen about 5 days after ovulation. It takes time for the egg to travel down to the uterus (unless it’s a rare ectopic pregnancy). Then it takes atleast 2 days after implantation for your hcg to be high enough to detect.
