Some women seem to know they are pregnant from the moment of conception; others have very early signs that tip them off. As hormone levels increase rapidly during very early pregnancy your body will start to go through a lot of changes. Some women start to feel symptoms as early as implantation when the embryo attaches itself to the uterus (6-12 days after ovulation). Others will begin to feel symptoms around when they period is due (12-14 days past ovulation).
Well, I experienced sore breasts & enlarged breasts about 7dpo. Also an increase in cervical mucus of a yellowish creamy color. I also had just a "feeling" that i was pregnant but nothing until about 7 dpo.
I had tender breasts, tiredness, period like cramping about 5-6dpo. Felt different from normal, had a feeling i was pregnant.
Women usually show signs of pregnancy once the Embryo has implanted in the Uterus and started releasing HCG. This occurs around 8-12 days after sex. During this time women also experience implantation bleeding.
Late bloomers experience symptoms later in pregnancy. Usually after they've missed a period.
