Before menstrual delay it is possible to notice some symptoms that may be indicative of pregnancy, such as sore breasts, frequent nausea, cramps, mild abdominal pain, or excessive tiredness for no apparent reason. However, these symptoms may also arise for any other reason or be indicative that the menstrual period is close, not necessarily being a sign of pregnancy.
To confirm whether the symptoms are indeed indicative of pregnancy, it is important that the woman waits for the delay of menstruation and goes to the gynecologist or do urine or blood tests, to identify the pregnancy-related hormone, beta-HCG. Learn more about the hormone beta-HCG.

Pregnancy symptoms before delay
Some of the symptoms that may appear before menstrual delay and be indicative of pregnancy are:
- Pain in the breasts, which happens due to increased production of hormones, which leads to the growth of the mammary glands;
- Darkening of the areolas;
- Rosy bleeding, which can happen up to 15 days after fertilization;
- Bloating and abdominal pain;
- Excessive tiredness for no apparent reason;
- Increased frequency to urinate;
- Constipation;
- Frequent nausea.
Pregnancy symptoms before menstrual delay are relatively common in most women and arise due to hormonal changes that occur after fertilization, mainly due to the production of progesterone, which increases soon after ovulation in order to preserve the endometrium and allow the implantation of the fertilized egg in the uterus.
On the other hand, these symptoms may also appear in the premenstrual period, and are not necessarily indicative of pregnancy. Therefore, in case these symptoms arise, it is best to wait for the menstrual delay to be confirmed and then perform the tests that confirm the pregnancy.
