Confused

So today is cd26. So not well vomiting if I eat. Have a dull pain that comes and goes in my lower tummy with a burning back super tired and no energy. My cm is creamy but more watery then thick. I have no idea even if I did ovulate this month as my opk keeps giving me a negitive the second line is very visible but still negitive. I have attached my chart and my bbt chart as well. So even if I did ovulate won't know how many days past ovulation. 4 more days before period is due yet still no sore boobs. Please going mad. Advice please
