Maybe. When you ovulate really depends. I had a miscarriage a little over a month ago and got my cycle back almost a month later exactly.
Just to add my levels were not very high to begin with!
My level was at 0 on Friday the 15th after my blood test! So that would mean i should either be ovulating or about to right?
Discharge can happen for a lot of reasons, however I doubt that it's due to pregnancy. The main reasons being you only had sex a week ago, and you generally don't ovulate that soon after a miscarriage. More than likely your hCG levels are still dropping and until they're under 5 you won't ovulate.
