Positive OPKs again this month?? Confused with my body.

I ovulated around October 1st (CD 21) or so I thought. Fast forward to the last few days and now I’m getting positives again?? Ended up testing because I was feeling slight cramps and twinges, similar to how I feel around ovulation time. Usually I ovulate around CD 20 and my cycles are around 35 days, but that varies as I’m still breastfeeding.

Side note: the last test (today) is slightly yellow because I started an antibiotic yesterday to treat a UTI and it can cause discoloration to your urine, so it is not dry just discolored.
