General Information
Pregnancy is an event can occur regardless of if consent is given. The week by week breakdown of what occurs during pregnancy will be written from a second person point of view, without gendered terminology, and with an entierly neutral connotation.

FIRST TRIMESTER
Week One
The start of your pregnancy is measured by the last day of your most recent menstrual cycle. Due to this, you are technically not pregnant during the "first" week of your pregnancy. Therefore, you will not experience pregnancy symptoms. However, you may still experience PMS symptoms.
Due to the measurement of pregnancy using the assumption of you having a standard cycle, your estimated due date may not be accurate if you have an irregular cycle.
If you plan on remaining pregnant and raising a healthy baby, it is advised to take folic acid and iron supplements. When choosing prenatal vitimans, options with a minimum of .4 mg (400 micrograms) of folic acid are recommended.

Week Two
You are ovulating during this week, and will experience the symtoms associated with ovulation. Due to how pregnancy is measured, you are not technically considered pregnant during the second week of pregnancy. Even if you conceive during this week, you are considered two weeks pregnant. If a sperm manages to travel into your vagina, through your cervix, through your uterus, into one of your fallopian tubes, and then penetrates one of your eggs, you will become pregnant.
If you are trying to get pregnant, having as much sex as possible during this week will increase your chances of becoming pregnant. If you want to try to calculate your own due date; add seven days to the first day of your last missed period, then subtract three months.

Week Three
At three weeks pregnant, you are officially considered pregnant. You may experience light vaginal bleeding known as implanation bleeding (as it can occur when the fertilized egg implants itself on the uterus lining). You may experience an increased basal body temperature. You may experience mild cramping or lower abdominal pressure as your uterus begins to expand. You may start to experience a heightened sense of smell, and a metallic taste in your mouth..
At this stage the "baby" is so small that it can be compared to the size of a poppy seed. The actual size at this stage, however, is approximately 5x smaller than a poppy seed. More accurate words than "baby" to refer to this tiny ball of cells are zygote and embryo. It is still too early for a pregancy test to show up as positive.

Week Four
Symptoms experienced during this week can be very similar to those experienced shortly before a typical period. These symptoms include breast tenderness, headaches, lower backaches, and nausea. Your "baby" is less than 2 millimeters in size. The placenta is starting to form.
At four weeks, you are finally far enough along to take a pregnancy test, and for that test to show up as positive. If the test is negative, and you still suspect that you are pregnant, wait one week before taking another test.
