TMI cervical mucus during high fertility

So not sure how well you can see it on the toilet paper but I tested high on a clear blue advanced ovulation test this morning and then after sitting on the toilet for some time playing on my phone I saw this long string discharge having from my lady bits and dangling almost into the toilet water. This happens to me quite frequently and I was just wondering if it happens to anyone else and if it looks like normal cm during fertile window?
