Help!! TMI

So in November my period only lasted 3 days and was superrrrrrr light. Mostly dark brown/pink and barely required a tampon/pad and had maybe only 2-3 small clots in it. Nothing like my usual periods where I change tampons at least 2-3 times a day. This month my predicted ovulation date was around December 3. And I had symptoms prior to the third like EWCM on Nov. 29 and one sided abdominal cramping. On December 9 I had a small amount of brown discharge, yesterday I had nothing and today I had a strange clot after I went to the bathroom. It was a very small blood clot and seemed like it was very stringy or had strings attached to it ? I’ve never ever had anything like this before and was wondering if anyone has had something similar. I’m not on any birth control and my husband and I BD a few times a week. I haven’t taken any kind of test as I thought it would be too early and was going to see if December AF showed up but I’ve never had these weird spotting experiences before! Any input is greatly appreciated!
