Confused by Mid-Luteal Bleeding Post-Loss — Could Use Some Insight

Hi everyone, I had a miscarriage earlier this year after IVF (D&C in March) and we’ve been trying naturally since. I usually get a solid smiley on Clearblue Advanced, but this cycle I only had flashing — even though I had clear ovulation signs: ovary pain, fertile CM, and night sweats. We timed intercourse well and felt hopeful.

Around 4–5DPO (CD21), I noticed internal pink/brown discharge when wiping. At 5–6DPO, I had a brief episode of bright red bleeding with tiny clots/tissue, then it eased into watery pink/red spotting. It never turned into a full flow. No cramps at all, just mild pain when straining for a bowel movement. Breast tenderness started the next day.

I’m now on CD23, and the bleeding just doesn’t feel like my normal period — which is usually heavier, darker, and more painful. I’m unsure if this is a weird early period, breakthrough bleeding, or possibly implantation (though the timing and nature are throwing me off).

Has anyone experienced anything similar? I’d really appreciate any insight — feeling a bit stuck in limbo.
