Pregnant after mc?


So last month I miscarried at 5w6d had some bleeding for 2 days with a few clots went to have a scan had an EXTERNAL SCAN only was told unfortunately what I hadn't wanted had happened so I took her word. But I'm now 5 days late and unsure whether to test or whether maybe my body is just trying to figure something out but ive got such sore boobs and been feeling sick and sooo sleepy! Need someone's opinions as SO just said to relax and wait for 2 months to see if period arrives!! I struggle with the 2 week wait let alone 2 months!! Also! Had a random call at 6 last night from someone at the hospital asking about the scan and asking me to take a test or something?
