Worried a little.

Janeal • TTC baby #1
Wondering if this is implantation bleeding or if my period really coming. So yesterday I felt light cramping and lower back pain and I felt a lot of discharge coming out. When I went to check it was light bleeding . So I went throughout my day just wearing a panty liner. Normally if it's my period if I woke up and went to check on my self it would be like bloody Marie down there lol but to my surprise there's nothing at all. So right now am a little confused. 😥😒.
