Confused when I ovulated

Dana

According the the OPK I was supposed to ovulate on Monday 1/25 so my husband and I BD 1/23 and 1/24. Unfortunately my husband sometimes.. has trouble performing.. so we couldn’t BD 1/25 or 1/26. I had ovulary pain 1/25. TMI- I applied preseed inside of me 1/25 evening but as stated, he couldn’t preform.. well 1/26 I had EWCM and now I’m concerned I ovulated 1/26 and not 1/25. Or could it be the preseed? Does it stretch like that if it sits in you that long? Or did I miss my chance :(
