When you’re trying to get pregnant, it’s natural to pay close attention to every change in your body. One thing many women notice is light bleeding or spotting before their period is due. This could be implantation bleeding, one of the early signs of pregnancy.
But how do you know if it’s implantation bleeding or your period starting? In this blog, we’ll explain everything you need to know about implantation bleeding — what it is, when it happens, how long it lasts, and when to see a doctor.
So what is implantation bleeding?
Implantation bleeding is light bleeding or spotting that happens when a fertilized egg attaches itself to the lining of your uterus. After ovulation, if a sperm fertilizes the egg, the egg travels to your uterus and implants into the thickened, blood-rich lining. During this process, small blood vessels may break, causing light bleeding.
It usually occurs around 7 to 14 days after fertilization — right around the time you’d expect your period. Many women may not realize they are pregnant and may think it’s the start of their period.
Implantation Bleeding Symptoms
Implantation bleeding is often lighter and shorter than a regular period.
Here are thecommon symptoms:
– Light spotting (pink, brown, or light red)
– Mild cramping
– Slight breast tenderness
– Light nausea
– Possible lower backache
– Mood changes or headaches (though not specific to implantation)
These symptoms may also resemble PMS, so taking a pregnancy test is the best way to confirm pregnancy.
When Does Implantation Bleeding Occur?
Implantation bleeding usually happens about 7 to 10 days after fertilization, often around the time you’d expect your menstrual period.
It’s one of the earliest signs of pregnancy, occurring even before a positive result on a home pregnancy test.
How long does it last?
Implantation bleeding typically lasts 1 to 3 days, much shorter than a normal period. It may come and go, and it usually stops on its own without treatment.
How Common Is Implantation Bleeding?
Implantation bleeding is quite common, although not all women experience it.
It is estimated that around 15% to 25% of women notice some light spotting in the first trimester, with some of this due to implantation.
How Can I Tell if It's Implantation Bleeding or My Period?
| FEATURE | IMPLANTATION BLEEDING | PERIOD |
| colour | light pink, brown or rust colored | bright red or dark red |
| flow | very light, spotting only | heavier, regular flow |
| duration | 1-3 days | 3-7 days |
| clots | no clots | possible clots |
| cramping | mild cramping | more intense cramping |
If you’re unsure, wait a few days and take a pregnancy test. It will give you a clearer answer.
When to See a Doctor for Bleeding in Early Pregnancy?
Light bleeding in early pregnancy can be normal, but it’s always best to check with your doctor, especially if:
– The bleeding becomes heavy
– You experience severe cramping
– You feel dizzy or lightheaded
– There is pain in your shoulder or lower abdomen
These could be signs of something more serious, such as an ectopic pregnancy or early miscarriage.
