Pregnancy after miscarriage?

Al

Ladies i really really could use some input, i had a miscarriage on November 7th and still havent got a period. I started taking the pill finished one pack, period didn’t come, a week later started second pack. So last week i took a pregnancy test and i got a faint positive line and just took another one now. I’ll post below last week and the now one. Please tell me what do you think, my hcg levels still going down? Could i be pregnant again (which im freaking out at the thought), or chemical pregnancy?
