What is Implantation Bleeding?
Implantation bleeding is a sign of early pregnancy and occurs after conception. Conception generally occurs in the fallopian tubes and the fertilized egg (embryo) then travels down into your uterus. At this point in your menstrual cycle, your uterus has prepared the lining to receive a possible embryo, and if you aren’t pregnant, the lining is what is shed during your period.
When the embryo attaches (implants) into your uterine lining, the slight disruption of the blood vessels can cause some spotting.
When does implantation bleeding happen?
Implantation bleeding typically occurs from 6-12 days after conception and is one of the earliest symptoms of pregnancy. It can be confused for your period as the timing of this spotting and your expected period may overlap.
Is Implantation Bleeding Normal?
Yes. Implantation bleeding happens in about 25% of pregnancies. It’s normal to have it, and also normal to not bleed at all. You may also experience it as a pregnancy symptom for one pregnancy and not another as every pregnancy is different.
What does implantation bleeding look like?
Implantation bleeding is typically brownish or slightly pink. It is also very light, more like spotting than blood flow.
How do I know if it’s implantation bleeding or my period?
The sure way to know is to see if you get a regular period or not – if not, it’s time to take a pregnancy test.
Other differences include:
Spotting:
- light bleeding, brownish or pink
- cramping is minimal or not there
- lasts up to 48 hours but may happen only once.
- If at all, only a panty liner would be needed.
Menstrual Period
- Up to a week of bleeding
- Cramping is common
- Soaks a few pads/tampons a day
- Bleeding starts heavy before getting lighter
- May contain clots
Other causes of vaginal bleeding
If you are experiencing bleeding outside of your normal menstrual cycle, it may have another cause. Other causes of vaginal bleeding may include:
- menstruation
- vaginal irritation
- endometriosis
- infections
- side effects of hormonal birth control
If you are experiencing bleeding or spotting that concerns you, it’s always best to contact your primary care provider.
