When Do You Start Spotting (Implantation Bleeding)?

During pregnancy, a pregnant woman can experience a lot of changes. Even some of these changes can occur at first week after conception. The process of fertilized egg that implants into the wall of a woman’s uterus can result some noticed light bleedings (familiar called ‘spotting’). So, when do you start spotting? How long does this implementation bleeding last?

Though light spotting due to implantation is one of the most common symptoms of early pregnancy, but there are also few women who don’t notice it. But overall, it is very common and even perfectly normal – so you should not worry about it!

Understanding the processes of your conception

Before jumping to the topic of spotting in early pregnancy, it is much better for you to also understand about how does your conception occur?!

The calculation for the age of pregnancy is more accurate if based on the day of conception. But in fact in many cases, many women don’t know the exact day of when they conceive. Therefore, the first day of last menstrual period is commonly used to start counting the age of pregnancy. In general, the time of conception is estimated from 2 weeks after the last menstrual period – particularly true for women who have 28 days of regular menstrual cycle.

The following are some major checklists of conception in pregnancy!

Ovulation

It is a term used to describe the time of when the egg is released from ovarye. In women of childbearing age, a group of eggs begins to develop & grow in small places called follicles (fluid-filled sacs) – and this process occurs each month inside ovaries.

Then about 2 weeks before the next menstruation, one of these eggs eventually erupts and releases from follicle. This egg is ready for fertilization (a starting point of pregnancy).

Thickening the wall of uterus

After the egg is released, then the follicle will start developing a phase called corpus luteum which then can trigger the production of certain hormones to thicken the uterus lining.

Where then the egg will go?

After the egg leaves the ovary, it then will move to a tube called fallopian tube. Once it reaches in the fallopian tube, it stays for about a day waiting & looking for a luckily single sperm for fertilization. So, there are now 2 possibilities; (1) no-fertilization or (2) fertilization that does occur!

The levels of your hormone then go back to normal, and eventually the wall of uterus that was thickened will fall in – as a result your menstrual cycle starts!

If there is a sperm that does go into the fallopian tube and then meets to the egg, there is high chance of conception to occur. Once the egg was fertilized, it changes in order to avoid other sperms to get in. The fertilized egg then will go to the uterus.

When do you start spotting in pregnancy – how long does it last?

For fertilized egg, it will stay in the fallopian tube for about 3 – 4 days. Then it moves to the uterus for implantation.

And as mentioned before, this implantation can cause light bleeding or often familiar called spotting.
