Do you feel abdominal pain during egg implantation?

Not implantation: At the time of implantation there will be a cyst on the ovary that released the egg that got fertilized. That cyst is norma (the corpus luteal cyst of pregnancy) and is necessary for maintaining the pregnancy until about 10 or 12 weeks gestation. That cyst could easily cause cramping, pain, pressure, bloating, and/or fullness.

Perhaps: There are many reports of "implantation pain" by women who undergo ivf treatment, for instance. No one has definitively come up for a precise medical reason as to why they experience this type of pain.

No: No, there are no consistent or reliable symptoms associated with implantation. 'implantation bleeding' is all the rage on the internet now, but that is also inconsistent and not useful for predicting pregnancy.
