Hi, I m 30 years old and I quit smoking cold turkey on jan 3rd after smoking a half a pack a day for 15 years. I got my period from jan 4th to the 8th. I had sex with my boyfriend on the 11th and a couple days later my breasts have been incredibly sore. As far as I ve been taught to count the days till I ovulate, I m not due till the 22nd. After quitting my body has been acting very strange... I ve been constipated, bloated, and craving sweets all the time. I ve read that smoking can effect your estrogen levels but I can t seem to find any info on hormonal changes since quitting. Are the swollen breasts and other symptoms just a product of my body trying to readjust itself... Or can someone experience early signs of pregnancy days after intercourse before the supposed ovulation date? Thanks!
