@seerly You can ovulate as soon as two weeks after a miscarriage. There's a max 30% chance in a cycle of pregnancy. A test is mostly accurate 14 days after sex and definitive 21 days after.
@taryn04 This sounds like your period. You'd definitely get a positive by 14 DPO. How are you tracking ovulation?
If your symptoms were related to pregnancy, a test would be positive.
