What is going on😭

So I was 7 days late, then 2 days ago I got a bit of brown when I wiped. Then yesterday I had 2 wipes of red blood so thought AF had come but now all day I’ve had no blood just a tiny bit of brown once in the whole day. I’ve had some small sharp pains. Can anyone make sense of this? The not knowing is driving me mad😭 I also had neg test when I was 5 days late
