UPDATE: My step daughters first period? Maybe?

So my baby is 10 almost 11. Real mom refused to have the puberty, period and growing up talk. So I have stepped up for her. She has been embracing all the beautiful changes, hair growing, acne, body odor, greasy hair and moody. I think my daughter had her light period before the real deal. My question is do you think this is her spotting before the real deal?

UPDATE:

So, I told biological mom what was going on. I told her she might be scared so she needs to tell her she knows what’s going on and to not be scared and she needs to make sure she has pads in the house. This was a week ago that we told her this. My wonderful beautiful daughter told her 3 days ago that this is happening and it got worse, she was scared and wanted help. Dad came to the rescue. He drove 3 hours to deliver pads! He didn’t tell me what he was doing to he only brought her the smallest package of pads possible. You ladies know the ones that only have like 8 pads in them. Mom only has tampons. Mom said she was going to go out and get some today.... IT’S NOT SOMETHING SHE CAN WAIT ON!!!! I don’t wear pads! I wear a cup a year ago when she started showing major signs of puberty I went out and bought pads. I periodically check on the pads stash to make sure she didn’t start and not tell me. I don’t want to force her to free bleed! Especially not for three damn days!!!
