TOTALLY TMI QUESTION

Af was July 31-Aug 6. After my husband and I had sex on and before the 22nd and we both came at the same time and lifted for about 5-15 minutes. I went to the restroom to go pee and when I wiped I notice a lot of really clear stretchy discharge. it lasted 2 days and now it's kinda tacky. We are ttc#3 Nd my period is every 30 days and lasts for 7. Can anyone help please and thank you?..... And I'm suppose to start on the 29th
