7 Days Late

I don’t know what to think anymore! My period is 7 days late, and I feel like I’m fishing for any sort of faint line so bad. It’s making me crazy! For the past 10 days I’ve had minor cramps, breast tenderness, lower back pain, some discharge, and today I started getting tension headaches. My husband said my boobs are huge right now! I’ve never been late before, so this is not typical for me at all. Has anyone experienced low hcg levels in early pregnancy and turned out to be pregnant? I’m holding out hope 🤞🏼
