Is it possible to get pregnancy symptoms 8 days before period is due?

Malika

I had intercourse during my ovulation time, from what the app tells I ovulated on Tuesday 14th November 17. I had sex with my partner on that day and on Saturday 11th November 17. After that I had sex again Saturday 18th November 17. I have been getting cramps every now and then but my nipples are sensitive and my partner noticed my boobs seem swollen, could this be a sign of pregnancy? Please help
