Chemical pregnancy but no bleed?

Hi, I had a chemical pregnancy a week ago, all pregnancy tests have been negative for a week now but I’ve still not had my period? The GP isn’t bothered about doing a blood test and just referred me to the early pregnancy unit who just said I’ll eventually get a period and to just test again if I’ve not had one by 2 weeks. I was getting pains last week that have on the whole subsided now. I just wanted to know if other people had, had a similar experience with a chemical and when you eventually got your period? I’m getting abit concerned now and just want to move on and try again but feel stuck in this limbo x
