Cessation of menses, in a healthy and sexually active person, is often the first sign of pregnancy. however, strenuous exercise, changes in metabolism and endocrine dysfunction, chronic disease, certain meds, anorexia nervosa, early menopause, or stress may also be the cause
amenorrhea
28
Occur in up to 80% of all pregnancies. Morning sickness describes the symptoms, but they may occur at any time of date. Distaste for certain foods or their odours may be the main symptoms. Begins between the first and second missed periods and usually improved by 12 to 16 weeks
nausea/ fatigue/ drowsiness
29
Tenderness and tingling as hormones from the placenta stimulate growth of the ductal system in prep for breastfeeding
breast changes
30
Common in early months of pregnancy. The enlarging uterus, along with the increased blood supply to the pelvic area exerts pressure on the bladder. Occurs in the first semester until the uterus expands and becomes an abdominal organ in the second trimester
urinary frequency
31
Fetal movement felt by the pregnant person, is first perceived at 16-20 weeks of gestation as a faint fluttering in the lower abdomen in a primigravida. Pts who have given birth previously often report quickening as early as 14 weeks

enlargement uterus/abdomen
36
Irregular, painless uterine contractions that begin in the second trimester. These give the sensation of the abdomen being hard and tense and they may become progressively more noticeable as term approaches and are more pronounced in multigravidas

37
A manoeuvre by which the fetal part is displaced by a light tap of the examining finger on the cervix, and then the part rebounds quickly. Uterine or cervical polyps may cause the sensation aswell
ballottement
38
Use maternal urine or blood to determine the presence of hCG.
positive pregnancy test
39
May be detected as early as 10 weeks of pregnancy by using a doppler device. When assessing, the pts pule rate must be assessed at the same time to be certain that the fetal heart is what is actually being heard. 110-160bpm
