Early signs of pregnancy, and when a test will actually tell you

It is the most-searched question in this whole season, and the honest answer is unsatisfying: the earliest signs of pregnancy are almost all produced by progesterone, which rises after ovulation whether you conceived or not.

So the symptoms are real. They just cannot tell you what you want to know.

The signs that show up first

• A missed period — still the most reliable early sign there is
• Breasts that are tender, fuller, or heavier than usual
• Tiredness of a flattening, unignorable kind
• Queasiness, with or without vomiting — often from around week five or six
• Needing to pee more often
• Food smelling wrong, or tasting metallic
• Light spotting around the time a period would be due, which some women have at implantation and many don't

Every one of those except a missed period is also a premenstrual symptom. That is not a flaw in your body's signalling. It is the same hormone doing the same thing in both cases.

What tests actually measure

A pregnancy test detects hCG, a hormone the body starts producing once an embryo implants. Levels rise quickly in the first weeks and peak around nine weeks — which is also, not coincidentally, when nausea peaks.

Implantation usually happens six to twelve days after ovulation. Before it, there is no hCG to find, however pregnant you are. That is why a test taken too early is often negative in a pregnancy that turns out to be perfectly fine.

An early negative is not an answer. It is a measurement taken before there was anything to measure.

When to test

• The day your period is due, or after — a test then means something
• First thing in the morning, when urine is most concentrated
• If it's negative and your period still doesn't come, test again in a few days rather than assuming
• A faint line is a line. Tests don't produce faint positives by accident

The signs that mean call today

A handful of symptoms in very early pregnancy are not ordinary and should not be waited out.

• Sharp or severe pain on one side of the lower belly
• Pain in the tip of the shoulder
• Dizziness, faintness, or feeling suddenly unwell
• Heavy bleeding, or bleeding with pain

Together, those can be signs of an ectopic pregnancy — one growing outside the womb — which is uncommon but serious and needs same-day care. You do not need to be certain to call.

About the searching

If you have been reading forums at midnight comparing your symptoms to strangers', you are in enormous company. Nearly every woman who has tried has done it, and it never once produced an answer for any of them.

Decide when you'll test, tell one person, and put the phone somewhere else. The answer arrives on its own schedule, and the searching doesn't shorten it.
