Early pregnancy signs are felt by many women even before they miss their menstrual period. However, most of the typical pregnancy signs and symptoms are directly related to the pregnancy hormone hCG (Human Chorionic Gonadotropin), which rises after implantation several days before the missed period.
Small amounts of hCG enter the blood stream several days after implantation, about 8-10 days after ovulation. Thus, typical pregnancy signs and symptoms typically do not appear until the hCG has reached sufficient levels which is about 1-2 weeks after you miss your period (3-4 weeks after ovulation, or 2-3 weeks after implantation), at a time when the hCG has risen enough.
Nothing will really confirm a pregnancy with sufficient confidence and can be considered among the 100% definite pregnancy signs except a positive pregnancy test.
A blood pregnancy test can be positive several days after implantation, while a urine pregnancy test is usually not positive until 12-14 days after fertilization or about 7+ days after implantation. The first pregnancy signs and symptoms and the time of their appearance are listed here:
An elevated BBT curve for 15+ days without a menstrual period
|Timing dpo=days after ovulation||Pregnancy Sign and Symptom|
|Implantation Day: 6-12 dpo|
|10 dpo||A positive blood hCG pregnancy test|
|14+ dpo||A positive urine pregnancy test (HPT): As early as 10-14 days after ovulation/fertilization or 3-4 days after implantation. The more sensitive the HPT the earlier the pregnancy test will be positive.|
|14-21 dpo||Nausea and Morning Sickness|
|2-3 weeks dpo||Nipple or breast tenderness|
|3-4 weeks dpo|
|1-2 months dpo|
|3 weeks dpo||Ultrasound pregnancy confirmation|
|4 weeks dpo||Fetal heart beat|
