Miscarriage and possible faint line...

Cari • Mommy of a 5 1/2 year old girl and 2 1/2 year old boy. Ready to complete our family!
So, I had a miscarriage on January 28th, after trying to conceive for over a year and a half. We decided to just continue what we have been doing. I haven't gotten a period and my boobs were super sore today but I am having cramping. I have no idea what to think. I see another line but no pink. What do you think?
UPDATE: It is POSITIVE!
