early symptoms or not?

he always pulled out, my period has been regular in past months and it's due to 25 but few days ago I started to have transparent discharges, tonight till now I feel belly and breast bloating, breast look actually fuller than always and I feel like something heavy on belly. today I also get nauseated while drinking coffee and smoking cigarettes (even the smell of both makes me feel sick). I also slept all day long and theres no reason why because I m not working rn. they look like symptoms but I think it's too early for them to show up. sorry for my English I hope you girls can understand and advice me asap ❤️
