Frustrated

Currently TTC and I'm at a point where I'm 10 days late for af. I'm showing loads of signs and symptoms of being pregnant even had what I thought to be implantation bleeding a week ago. I've had a couple of tests show up with vvvvvvvvf lines so took a clearblue test and it's saying not pregnant. my sister has said some people can be like how I am at present and it takes them 10weeks before they get a positive cause of their hcg levels being too low I'm so frustrated and I can't see a doctor till I'm off work in over a week 😢 I didn't realise just how stressful Ttc could be and how much of a toll it takes on you
