Peak and then still positive 3 days later?

Angela

I took a test for the first time Friday afternoon and it was very strong. Then I took another one today (monday) thinking it would be a complete no (just trying to learn my body) but I believe it's still positive? Sorry for the gross info but mucas has stayed white entire time (today quite a lot of it) but last two months (3rd month ttc) I've never noticed it as a clear eggwhite that alone is making me wonder if it's not going to be easy for us. First pic is Friday, last pic is today (monday)
