Pregnancy related? Help!

Hi everyone. 5 weeks today I got my implant removed. A week today I started bleeding. I only noticed when I wiped and saw a light pink/light red blood. It got heavier and it lasted 4 days so assumed was my period. On the 5th and 6th day it was much lighter and it was either really old blood as it was really dark brown, or it was discharge. Yesterday I had no blood and no discharge. Today I have felt really ‘wet’ down there. Sorry if this post is TMI. Today i have noticed this in my underwear...

The darker part is actually brown. The picture doesn’t really show the true colour. Just wondering if this is possibly early pregnancy related? Anyone else had a similar experience and ended up having a healthy full term pregnancy? We have been having unprotected sex for just ofer 2 weeks now. I have 2 pregnancy tests but not sure when to take themas ive always had irregular periods. Any Opinions/advice is helpful! Thankyou in advance!
