Nothing at all

I am 11 weeks 5 days today and it seems like I don't feel luke i am pregnant but i do have my baby bump now. Unlike the past weeks there are some slight movements that I feel. Though I watched some vlogs, some said they felt some movements some said it's just normal. I'ce been having headaches and there is a certain part at my back which is a bit painful esp if I sit more than 15mins. I am worried. Been longing to get pregnant for almost 15 years after my miscarriage 15 years ago and I just want to make sure i'll be fine. Does anybody have the same symptoms esp the no movement thing? Thanks.
