Something is definitely up this

Month. I’m 11 days late. A lot of signs of pregnancy like no period, headaches, enlarged and darkened areolas to the point where my SO said something, fatigue, nausea and aversions which is not normal

At all and had implantation bleeding after ovulation but no positive hpt. I’m seriously worried something is wrong or maybe an ectopic pregnancy. I’ve never just skipped a period I’ve had no anxiety or stress that could have affectedMe getting my period and I’m not sure what to do. I hate this so Much I just wish I knew what was going on 😖 I could be 3-5 weeks pregnant but no of low hcg? What one earth is going on
