Ahhhhh?? Thoughts? Is this ok?

So I have normal cycles, nothing out of the ordinary. Well my period ended over a week ago and I was beginning my fertile week... I have never bled before but today I did. It wasn’t a lot but it is alternating on/off and it was a mixture of spotting and flowing... is this normal? I felt fine today, just tired. Now that I’m bleeding I feel like I’m getting cramps.... has this happened to anyone before?
