Multiple positive opk on Clomid

Hi! So I took my 2nd round of 50mg Clomid on cd 5-9 cd 12 and 13 got peak/smiley face on clear blue digital then today cd 15 took another opk same time of the day as the other ones and got another smiley face. Is this possible to ovulate more than once in one cycle when taking Clomid? Or is this just a false positive due to Clomid? Anyone had the same experience? Pls comment and let me know your experience. Would call my doctor tomorrow and ask as well... Just want to hear from other person who experience this. Thanks in advance.
