is this a new pregnancy???

This is the same picture for all pics. Top was fmu yesterday. Bottom one I took today at 3pm. Is it me or did the line get darker?? Also I am doubtful as I feel like my period is coming but can't help but think what if 💁🏻 I am 4 weeks past d&c what if it's left over hcg right? But why is today's darker??. What should I do?? Please be kind 😔
