help!! can you ovulate twice??

Rebecca • 27, TTC my second baby. I love my husband for giving me baby #1 who is the most amazing gift in the world!!

Hi I got a positive OPK on CD14, a week before that I was experiencing EWCM and watery, On the night of CD14 I had cramps and sharp twinges, CD15 which should have been ovulation day my cm turned creamy and lots of it and it's been like that ever since, I didn't chart my temp because I had a cold so was unreliable, I'm on CD20 (5DPO) and I just got this I'm assuming it's positive, I don't even have fertile cm it's still creamy, could it be I didn't ovulate first time round? Or can you ovulate twice?
