Period or not?

Be
Hey ladies so last month we had a chemical pregnancy which resulted in a normal period... I'm due nowish (I have irregular periods) 
yesterday I started having brown spotting only when I wiped, then hubby and I had sex and I bled like on my period so I inserted a tampon and 6 or so hours later took it out to change and there was nothing there, hubby and I have had this happen 3 times since then all with the same outcome.
​Kinda confused :) and since I have some awesome girls to ask, I thought I'd ask your thoughts :)
​Period or not period lol
