I wish I could give a class on pregnancy, but I'm too busy now

Sorry...
In short detail, pregnancy is not a simple thing... aside from
physiological changes in your body, you have to apprehend things
that are deadly to both mothers and fetus including pregnancy
induced hypertension, gestational diabetes mellitus, premature
labor, preterm prelabor rupture of membranes, rhesus
incompatibility, transmission of infectious diseases, infection
proned, immunosuppresion, postpartum hemorrhage, postpartum blues /
depression, ectopic pregnancy, tubal pregnancy, intrauterine growth
restriction and well, there are a lot more...
