Bleeding after chemical ?

So I think I’ve had my first chemical. I had what I think was implantation bleeding at 11DPO followed by vfl 12DPO. First beta was only 22 and two days later it was 13. I’m now 18DPO and a week late for my period. I took an expired test as that’s all I had but it looked pretty negative. Any idea when I add hours start bleeding? I’m ready to just try and move on 😢
