Is this implantation bleeding??

Good morning ladies,

I need your help and expertise!

I started my period two days ago but it’s abnormal. I have always had a heavy flow. This time around it has been very light. It’s so light that I a small or even no blood on my panties. It’s mostly when I wipe. It’s a light red or brown. Last night I had some tissue like with light blood when I wiped. Is this normal? I’ve never had a light period. The only time I had a light period was once when I was i birth control but I haven’t been on it for a few years now. Help!!!
