IMPLANTATION? 7dp5dt

So I received a very positive test this morning, meaning a visible line not insanely dark.

I’ve been having cramps and sharp pains and then after the test this morning I started to have spot marks when I wiped! Pictures below.

Please tell me this is implantation and not cause for concern.

I have on estrogen 3x/day and IM progesterone shots nightly.

I am currently 7days post a 5 day blastocyst transfer
