Chart after D&C

Not TTC this month as I had a D&C on May3rd but looking for your thoughts on my weird chart. My HCG dropped to 5 on May 22 (CD 20). I had massive amounts of EWCM on CD 19, 20, and 21, but never a super strong positive opk (at least not as strong as the positive when we got pregnant). My temps also aren't as high as they usually are after ovulation. I'm normally over 98 degrees. BUT there is a dip (normal for day of ovulation for me) and a rise therafter.  Do you think I've ovulated???
