Implantation, or imp, in pregnancy and bleeding do go together. Spotting can happen when the fetus implants in your body. Details on bleeding during pregnancy.
Implantation bleeding, also referred to as imp bleeding or implantation spotting, occurs during the third of fourth week of your pregnancy. You can spot during your pregnancy, especially in the first trimester. Not all women experience it, but those who do report it as light spotting.
While implantation bleeding is not threatening to a pregnancy, experiencing heavier bleeding or cramps is not normal and you should seek a doctor’s aid.
Imp Bleeding during Your Pregnancy: What causes it?
Implantation is the actual process of a fertilized egg attaching itself to the lining of the uterus. It can only happen during a specified time in your menstrual cycle and fertilized eggs (zygotes) that do not implant themselves into the uterine lining are not viable and will result in a miscarriage.
Generally, zygotes that miss implantation do so because there is something wrong with them, and the safety mechanism of the body is to not grow a fetus that has something wrong with it at the very first stage of pregnancy.
As the zygote is floating in the uterus prior to implantation, it gets its nutrients from the uterine cavity. When it is implanted into the uterine wall, gets its nourishment from the uterine cells. By week four of the pregnancy, the fetus has developed an amniotic sac and a basic placenta.
These both will protect and feed the fetus throughout its development. The placenta is a permeable barrier that has multiple functions and works to:
- Filter in nutrients for the fetus
- Filter out waste products produced by the fetus
- Prevent the passage of harmful elements, bacteria, viruses*
The amniotic sac is filled with amniotic fluid that cushions the baby in a sac of liquid. The amniotic fluid is also where the nutrients transported by the placenta are deposited for the fetus to absorb. Some bacteria and viruses can cross the placental barrier, including Listeria monocytogenes, Rubella (German measles), Varicella (Chicken Pox), and Parvovirus B19 (Fifth Disease).
Imp Bleeding during Your Pregnancy: Differentiating between Imp Bleeding and Your Period
Imp bleeding tends to resemble your period, but it differs in that it will be out of time for those who have regular menstrual cycles. The spotting will also be of a darker color, closer to dark brown or black, as the blood excreted is older; it is not fresh or new blood.
Bleeding during the First Trimester of Your Pregnancy: What Else It Might Be If It’s Not Imp Bleeding
Imp bleeding should not continue for weeks and if it does, it may be a signal of an ectopic or a molar pregnancy. If you are not pregnant, then bleeding that resembles imp bleeding can be a whole host of other conditions including: your period, cervical changes, miscarriage or cervical cancer.
