pregnancy maybe? ***tmi***

i have one kid. i am super careful most of the time i watch my discharge and everything HOWEVER this month i had unprotected sex the day after this app says i ovulated and usually leading up to my period i have creamy discharge but its 6 days to period and its watery. ive been super bloated and have gas amd light cramping and light nausea off and on usually i just have moody pms symptoms...did anyone experience that before they found out they were pregnant? i had a rough first pregnancy so i blocked pretty much everything out and cant remember....scared to take a test
