Please help

Patient: Hello I was just wondering if you know if overdosing can make your periods late because I am now 2 days late and if it can’t I need advice as my bf and I had unprotected sex on the 22nd of May however I did take the morning after pill however I know this is not always effective. Should I wait to see if I get my period or just get a test incase and should I tell the person I had sex with incase I need support!? Thanks x

Symptoms: Tiredness, slightly nauseous but I’ve not been sick
