thanks to everyone who responded. I've stopped eating sesame bagels and still see some. In fact, I am sure they are not sesame seeds since they are bigger than the seeds I eat. Therefore, they are most likely parasites and that can explain how I've been feeling for the past years.
I've past so many tests including worms and parasites tests in the hospital and all were negative. I guess the tests they make you past are not exhaustive.
The Bentonite seems to kill them since they appeared since I take BP shakes.
I will most likely take paraway to get rid of them all,
If anyone can confirm if they know what kind they are (or if they are eggs?)?
