Help pregnant immediately after miscarriage

Oh my god I am so stupid and managed to get pregnant straight after miscarriage before my period came back. Have I put my body and my new baby at risk this early? I ovulated two weeks after my miscarriage and got a negative pregnancy test and myself and my husband got carried away the next day. I am now getting a positive test two weeks since ovulation. I am so scared at what I have done. I can’t even ring the doctor yet with embarrassment. Has this happened anyone at all out there? 🙈
