Is this positive

So Saturday I was officially a day late and I took a test

Then I had sex with my boyfriend and I started to bleed and had cramps all Sunday I took another test and it looked like this

I looked at it again today after it dried (there was a faint line there Sunday) but now it looks like this

and Monday and today I am still bleeding . Not really like my normal period because I usually use a lot of pads. But Sunday little specks of tissue was coming out and Monday this came out

It keeps happening. I took another test today
