Not too sure

I have been trying to get pregnant for about two months now. I was due for a period on the 5th of this month but started yesterday, most of the blood yesterday was dark, so of course I thought it was implantation bleeding. Most of it was a brownish color but some was pinkish. This morning I wake up and I do have a little blood in pad but most of my blood comes out I go to pee. Not sure how to explain it. This is happening every time I sit on the toilet. First picture is today and last is this morning. Someone explain because this isn’t normal for me. (Edit) I have also been having bad cramping which I never cramp during a period. My body literally aches.
