Periods after miscarriage

Hi, I’m new here and after some help regarding my periods after a missed miscarriage I had in feb. I had an erpc at the beginning of April due to remaining pregnancy tissue. 6 weeks to the day of the procedure I got my first period. After using opk s I ovulated on the 2nd June, was over the moon, but today I have had what looks like my period. It’s a medium to heavy flow and obviously I’m so upset and confused as to why I’m bleeding. As I’m 5dpo. I Would be sooo grateful to hear from anyone that has been in the same situation or knows any info and can help. Thank you
