Could this be it???

My husband and I finally decided to try for our second baby!! I haven’t had a period since before I got pregnant, which was July 2017. Afterwards I went on the depo shot and still didn’t have a period. I quit taking the depo shot at the end of August. The past three days I have been bleeding, very lightly, but still there! Is this the start of my first period back?! Normally I wouldn’t be happy about this but getting my period back so quickly after stopping birth control makes me so excited to start conceiving!!!
