IVF baby spotting 5 weeks ** TMI **

Anyone else experience very mild light pink/brown spotting around 5 weeks pregnant?

I had some dark brown spotting around 4 weeks which I’m positive was implantation bleeding. Everything was fine and then about last night at 11 PM, I started having some light pink or tan discharge that turned into brown spotting and has been continuous throughout the day as I wipe. 

There’s been very few times where I wipe and not see some type of spotting today. I am worried about an ectopic pregnancy at this point. 😭

WILL POST TMI pics in comments as well. **
