Many women don't feel the symptoms of pregnancy during week four. However, about 50 percent of women will experience pregnancy symptoms during week five, and most women will notice symptoms around week six. If you are already experiencing pregnancy symptoms, they may include:
A positive home pregnancy test, or positive blood pregnancy test: the pregnancy hormone, human chorionic gonadotropin (hCG), is responsible for setting your pregnancy in motion and will be present in both your urine and blood.
Spotting: it’s possible that as the egg buries into the uterine lining, you will notice some light spotting called “implantation bleeding”. This may be accompanied by some mild cramping, but the bleeding will generally be lighter in both volume and color without a consistent flow. If you're concerned, reach out to your midwife or healthcare practitioner.
Tender or swollen breasts: while your breasts have a while to go before they become proficient milk machines, changes are already beginning and may result in some sensitivity.
Mood swings: hormone fluctuations may leave you feeling extreme emotions from joy to irritation; sometimes switching without warning. If your reactions seem to be irrational, know that your growing baby may be the explanation.
Morning sickness: this notorious early pregnancy symptom can vary drastically from pregnancy to pregnancy and despite the name may not be limited to the morning hours. Nausea may or may not be accompanied by vomiting and can be triggered by hunger, strong smells… or at times seemingly nothing at all.
Cramping: often associated with your period, cramping may set off your internal alarm bells, thinking that something is wrong– but it can be a perfectly normal symptom as your body stretches and relaxes into its new role as a baby incubator.
Fatigue: need a nap? Making a baby is hard work! Even in the early weeks, you may find yourself exhausted. Be sure to listen to your body and get some rest whenever you can.
Gas and bloating: pregnancy isn’t always glowing radiance. As your digestive system slows in response to increased progesterone causing your muscles to relax, you may experience bloating and gas (from both ends!).
