Ovulation and sex once??

I had a positive opk on the 25th.. my husband and my schedule is busy with work etc. we had sex on the 24th, that evening. Is there still a chance this could be our month? Seems like whenever I am in my fertile window life happens and we are busy!!! Any help is appreciated!!! Today I noticed my nipples are pretty sensitive and boobs are a little sore as well.. thanks!💕
