🤞I hope this is it

Ok so I have irregular periods. October 17th,2019 . I found out I was pregnant 3 days later I had a miscarriage. It took my SO and I 3 years and 10 months to get pregnant the first time . On CD 27 and CD 28 I had spotting/ Brown Discharge. It only happened once each day. Now I’m on CD 32 and all I have had was white discharge and stretchy clear/white discharge when I check my cervix. My cervix are also high and closed I took a test this morning but it was negative. Any idea what it could be ? And no I have no idea when I ovulated .
