CONFUSED IF PREGNANT OR NOT? PLEASE HELP

Sim

Hey ladies I am fairly new on this app also with finally decided to conceive. We are married for 5 months but together 1 and half year. Anyways we just decided a week before my periods were predicted that we will make babies. I am sexually active. My last periods were longest in my entire life which is 10 days Aug1-10 just spotting not heavy. My doctor said its fine if its first time i guess it was cz of stress. Now my ovulation window was gone we decided his cum Aug 23 and for few days we did including today. Now I am very creamy since last couple of days not sure how. And my prediction periods was Aug 30 and its Aug 31 night no periods yet. My average cycle is 28 days. Does this means is there chances of me being pregnant or what is going on? I did tested Aug 24 but was not pregnant. Will test tomorrow Sep 1 st i guess. But can someone help me in this ??please and thank you in advance.
