More line progression! Why am I soooo paranoid

I am almost 5 weeks pregnant, and 4 days late on my period. (15 DPO) Symptoms are: Cramping and backaches, tired, sometimes dizzy, some headaches and high sense of smell. I’ve also been having left hip pain (I had hip pain before being pregnant for years and it’s the same pain, just worse and more constant) I called my OB and she said as long as there is no blood, to not worry. BUT I worry about everything anyway 🤦🏼‍♀️ how is this all looking to you guys??
