Implantation of the fertilized egg to the endometrium happens within a day or two of fertilization. The zygote attaches itself to the walls of the uterus which can cause little bleeding or spotting with cramps. Tiny place of the uterus lining sheds off to give room for the fertilized egg. The zygote would get all the essential nutrient supply from the uterine wall. Zygote at this stage would be in the form of few cells which would multiply rapidly.
Implantation bleeding is the spotting that happens after the fertilized egg attaches itself to the uterine wall. Many women can confuse this with normal menstrual bleeding. And you will know about the bleeding when you wipe inside. There is clear difference between implantation bleeding and menstrual bleeding. Though both are brown or red in color, still in the implantation bleeding only few spots can be seen.
1. Timing – Implantation occurs after the ovulation which happens 14-16 days of the menstrual period. During the process of ovulation, eggs are released from the fallopian tubes to get fertilized with a sperm. After the eggs are released, they move towards the uterus, wherein it meets the sperm, to get fertilized. It might take anywhere from 7-10 days for this movement. You need to remember that you have already got conceived before your next period date.
For a woman with menstrual cycle of 28 days, the ovulation would happen anywhere from 14th to 16th day. The ovulation process lasts for about 12-48 hours during which the environment is highly suitable for fertilization. But even seven days after ovulation a woman is potentially fertile. So, if you have spots and mild cramps well in advance (before 7-10 days) of your regular period, it can be implantation bleeding.
