Any insight...

So I just had 5 days of wired spotting, it would do dark red/brown to light pink. Only one time was it bright red and that's when I passed a dime size clot. I had no pain or cramps either during this but I was super hormonal and super exhausted. It's 2 days past my "period" and I'm still extremely exhausted, mild headaches and now I am seeing this discharge. WTH?! (Edit I did have sex with my husband yesterday morning, that's what the spotting is) could any of this be pregnancy, or just weird period this month? Also why this discharge so close to when I ended my "period" I'm confused. It was super stretchy too.
