Question about ovulation and mucous

Hi guys, the last of my EWCM finished about 3 days ago and this afternoon I'm feeling bloated so much that I had to unbutton my pants as soon as I left work haha. I have not eaten anything that would normally make me feel bloated and I don't know if I've ovulated as I haven't used an opk and haven't had a temp rise on bbt chart yet. Anyone have any ideas or similar situation? Do you think I've already ovulated? I keep reading that ovulation usually occurs on the day of or day after the last of the EWCM.
