Hmm.......?

So on May 19th I found I was pregnant (confirmed @ doctors approx 4w4d) and that Saturday (few days later) I started bleeding.. Chemical pregnancy (doc confirmed very low HCG). I counted that as my period, which meant it was exactly a week late. I am now currently on my next cycle (usually being 28days) and that would mean my period is due tomorrow (21st June). I did test after I had stopped bleeding after chemical pregnancy and got a negative test so HCG was not present anymore. With that short pregnancy I had sore boobs, bit of cramping, and bloating and of course a positive test. This time round, being supposedly the day before I'm due, I have sore boobs but not much else.. Is it still possible? I took a FRER and I swear I can see an extremely faint line but not sure.. :-(
