Baby movement.

Hi y’all. Just wanted to state first off this is my first baby and I’m super excited and nervous all at the same time, so I’ve had a few questions that my mom can’t answer for me. Over the past weekend my baby was moving sooo much and kicking soo hard, but yesterday it is like he’s not hardly moving and today I will feel small kicks. I have had like teeny Tiny spots of blood randomly too lately. Is all of this normal? According to this app I am around 22 weeks. Sorry if this sounds dumb, but just wanted some input.

Note: I will be addressing this with my doctor when I go next week as well.
