Im 26 and have an 8 year old son.
Had sex on the first night of my period , the next morning my period stopped , I've had sex on my period before but it has never stopped and always lasted 5 days. Since 2 days after my period stopped I have had a milky white discharge and always feeling really wet this is still on going , I have never been that wet before , 2 more days later had a day of very hot flushes and sweating to the piont of having to strip down to shorts and vest and its December lol 8 days have now gone by since we had sex that night. I know I can't test yet but is it possible for me to be pregnant ?

Yes it can be possible. Most likely it is not that and more likely an infection or even a hormone issue. But now you as all women play that waiting game till next month and see if you get that period.
