Early signs of pregnancy include tender breasts, swollen breasts, fatigue, moodiness, food aversions and cravings. Other signs include frequent urination, nausea, vomiting and being lightheaded, as stated by WebMD.
The exact signs presenting during pregnancy will differ for each women. Some women do not experience any signs until after their first missed period while other women start having signs much earlier.
A woman will often experience heavy breasts that may be painful to the touch due to hormonal changes as early as a few weeks from the date of conception. This increased level of hormones also leads to fatigue and moodiness, as stated by the Mayo Clinic.
For most women, some symptoms, such as nausea and vomiting, begin to subside by week 12 to week 16. On rare occasions, a woman may experience those symptoms through most of the pregnancy. In cases where a woman loses weight due to excessive vomiting, medical intervention may be needed.
Many of the signs of pregnancy can be related to another condition, including menstruation. This is the reason a missed period is often the biggest sign that a woman is pregnant. If a woman suspects she is pregnant, she should be tested as soon as she misses her first period. This enables her to seek medical attention early on in the pregnancy.
