8 weeks after miscarriage

Hannah ✴ • 23. Betrothed. Montreal. Force of nature.
It's been 8 weeks since I got a negative test resent after an early miscarriage (4ish weeks). I still haven't ovulated nor have I had any more bleeding, and I'm wondering how long I should wait before going to a clinic and asking for progesterone pills. I've had some slight cramping, but nothing more. Could something be wrong?
