Any advice?!?

So frustrating, I have every symptom that points to being pregnant. However I have 2 beautiful kids but the last 3 years I've had 3 miscarriages and one ectopic at 10 weeks which lead to my tube being taken out along with the baby 😕. I have headaches every day, I'm a strict pop drinker only and it's been nothing but water the past week. Tried taking out the trash yesterday and about threw up, my bobs feel bigger and started hurting bad yesterday. My period is due Saturday but I'm 10 dpo today and had faint pink spotting only when I wiped once yesterday morning. Later that night a few tiny red blood clots. Then today semi pink and brown spotting. I have to eat breakfast when I get up which I never do. Took a test yesterday and came up negtaive. I was 9dpo was it too early to test? I'm scared this might be the start of af but I haven't had cramping which i normally have severe cramping and back ache the day before af. But hoping it was implantation...
