When Pregnancy Symptoms Come and Go

It’s understandable to feel anxious when symptoms fluctuate. It can’t help but bring up worries as to whether the pregnancy is progressing as it should or if there is a problem that requires immediate attention.

By knowing what is normal and what is not, you can alleviate many of these concerns and be better prepared to manage the occasional ups and downs that can accompany pregnancy.

Normal Changes in Pregnancy Symptoms

The symptoms of pregnancy can vary from person to person (and from pregnancy to pregnancy). While some people, for example, will never experience a day of morning sickness, others will feel nauseous and ill for weeks or even months.

The same goes for the other common symptoms, particularly during the first trimester. These include breast tenderness, frequent urination, cramping, acne, food cravings, bloating, dizziness, mood swings, back pain, and constipation. Some people will have many of these, others just a few or none; and they may not happen consistently.

Frequency Varies

The frequency and intensity of these symptoms can be highly variable, and, quite honestly, you can’t be expected to feel all of them all of the time. There will be days when you may experience cramping and frequent urination and others when you’ll have sudden cravings for certain foods.

There will even be days when you’ll be entirely symptom-free. This is all perfectly natural and usually of little cause for concern.

In some cases, the symptoms may not so much disappear but rather become less noticeable as you begin coping with the frequent changes in your body. Over time, you may begin to better understand your mood swings or have found ways to deal with the rigors of constipation or nausea.

By the second trimester, many of the more profound pregnancy symptoms may begin to dissipate. Others will continue right up until the moment of delivery. Neither of these is considered a sign of a "less normal" or "more normal" pregnancy.

When to Be Concerned

There are times when changes in pregnancy symptoms warrant concern and investigation. Getting medical help right away is important.

Baby Is Moving Less

Chief among these is fetal movement. While it may be some time before you actually feel any movement (somewhere between weeks 16 and 25), if you notice any significant changes in activity moving forward, tell a healthcare provider right away.

A decrease in fetal movement, or a complete cessation of movement, may be the sign of an emergency situation. While other symptoms may decrease or subside as your pregnancy advances, the movement of your baby should not. There will be times when your baby may be quieter. But if any changes in an activity seem unusual, don’t hesitate to see your doctor or visit an emergency room.

Sudden Loss of All Pregnancy Symptoms

If you suddenly have no symptoms at all, this can be worrisome. This doesn't mean having a symptom-free day or two. Instead, it refers to a situation where you’ve been dealing with multiple symptoms and suddenly have none.

The sudden cessation of symptoms may be the sign of a miscarriage, especially if it happens during the first trimester (when most pregnancy loss occurs).

While it doesn’t necessarily mean that there’s a problem, it does warrant investigation should the change be sudden and extreme. Even if there are no other overt signs of miscarriage (such as abnormal bleeding or severe cramping), it is still important to get checked out sooner rather than later.

A Word From Verywell

While there are markers and milestones common to all pregnancies, the experience of pregnancy is highly individual. The severity or frequency of symptoms is not a clear indicator of how your pregnancy is progressing. It can be perfectly normal to have pregnancy symptoms that come and go, or to have no symptoms at all.

If ever in doubt, follow your instincts and speak with a healthcare provider. All it takes is a simple ultrasound to check the status of your pregnancy. It can put your mind at ease or, if there is a problem, allow for immediate intervention.
