On period but still could be pregnant?

Katelyn
Hey everyone! So my period this month has been weird! I started 2 days late, yesterday was day two of being on it and I noticed my flow was lighter than usual and today I am only spotting.... My period usually lasts for 4 days and the last day I spot. So i don't know! Could I be pregnant? I need other girls opinions! I haven't taken a pregnancy test or anything!
