Unsure what to do or think

Been 10weeks since proper period. And 5 weeks since I had very light spotting for two days. (Legit barely anything at all) took two pregnancy test both negative. Have the rod in my arm. Up until this everything as been on time and in a regular pattern. Last two weeks been queasy and sensitive to food and how much I eat and what I eat. Hot and cold flushes. Been really tired and one of my boobs has gotten sore over the last week. Need advice. Asap please??
