Hello, I have unprotected intercourse on 29.12.2019 during my ovulation. After 36h I took ellaone. In january I got my period on time on 15.01.2020 (it last 3 days with medium bleeding-first two days it was more bleeding and the 3-th day it was just spotting), but today I start to fell my breasts a little heavier and painful (just like before my period), but I am confused its early for pms symptoms (my next period should come on 11.02.2020-for 15 days, I usually feel pms symptoms a week before my period). Can I be pregnant, can be this sign of pregnancy after 5 weeks?
