Did I ovulate?

Hi everyone! So, I got off BC in June (started trying for a baby in July, but tracked my ovulation with LH strips starting in June). My cycle from June to July was 28 days with a strong positive on CD14. July to August and August to September were the same way (28 day cycle, strong positive LH strip on CD14). Anyway, this month, CD14 for me was this past Sunday. Saturday (CD13) my husband and I were out of town and I forgot to bring my strips, so I couldn’t test of CD13 like I normally would. I tested Sunday morning (CD14) when we got home and expected to see a positive, but...nothing. I tested again Sunday night, Monday morning (CD15) and Monday afternoon - all negative. Is it most likely that I ovulated a day earlier than I have the past three months and just missed the + test on Saturday? Or, did I not ovulate at all? My cycle has been SO normal with strong LH tests every months up until this point, so I was surprised I didn’t get a positive. I had EWCM starting on Friday (CD12) and still have it today (CD16). Thanks in advance!
