So I'm CD17 and 5DPO on a whim I decided to do another OPK and it came back positive, so I did a cheapie pregnancy test and it came back positive. Ran to Asda and got a CB Digital and it's saying 2-3 weeks. I had a MMC at the end of August and I have had a negative result since then to comfirm end of miscarriage. How can I possible be pregnant? Any idea whats happening to me? I'm a bit sceptical of it and don't want to trust the pregnanct test.
