Cervical mucus shows poor crystallization
Beading
Hormone responsible for poor crystallization in pregnancy
Progesterone
Presumptive signs of pregnancy
Cessation of menses Beading cervical mucus Chadwicks sign Changes in breast Skin changes — chloasma — melasma — linea nigra — striae gravidarum — spider telangiectasia Increased temperature
seen on glass slide, result of amniotic fluid leakage, arborization of ice crystals
Ferning
Endocervical gland hyperplasia and hypersecretory appearance which is difficult to differentiate from atypical glandular cells
Arias Stella reaction
Greater vascularity and hyperemia in the skin and muscles of perineum, vulva, vagina, and cervix resulting in violet color
Chadwick sign

Morning sickness
Fatigue
Frequency in urination
Quickening
slightly elevated clear or red patches that bleed easily seen on and just beneath the ovarian surface. Arise from subcoelemic mesenchyme or endometriotic lesions
Decidual reaction
Protein hormone secreted by corpus luteum, decidua, placera, brain, heart and kidney. Aids in remodeling the reproductive tract connective tissue to accomodate labor
Relaxin
Exaggerated physiological follicle stimulation. Usually bilateral, moderately to massively enlarged cystic ovaries due to markedly elavated serum hCG
