I’d say that although they are clear positives, they are still quite faint which could mean you are very early in the pregnancy stage. Some women do get BFPs this early (wish I was one of them lol) so it’s not unheard of! My guess is that you ovulated on time, but you have enough HCG to detect pregnancy... over the next week any more tests you do should become darker to as they will detect more HCG x
You don't need to do anymore tests. Those are positive. The reason you are advised to wait until your period is overdue is so you get a clear result. Nothing weird about getting a clear result slightly earlier than that.
Sites like this can make you nervous as well as informed because you read about all the stuff that can go wrong. It can be easy to forget that most of the time a positive test means a baby in your house next year
If it makes you feel better they're stronger positive lines than what I got 5 days overdue on my period from ovulating the day I was predicted to (also the only day we dtd). The days before that were all negative tests. Congratulations!
