7 DPO Symptoms?

Haven’t had any breast tenderness yet, but I have been feeling heavy in my stomach which I’m guessing is bloating. Also I’m noticing like hot flashes or something cause my face gets really warm off & on this morning. Is this normal?

Also got a BFN around 12Am last night. Still too early to test but was worth a shot 🤷🏼‍♀️
