Hello, and i hope I can help you today.
First of all, I want you to know that
pregnancy symptoms can only appear once a conception completely takes place and is implanted in the
uterus. At 48 hours after an act of intercourse, there is no significant production of any hormones of pregnancy, which is why even if you conceived, your pregnancy test which measures for the presence of pregnancy hormone) will be negative. Furthermore, your abdomen does not begin to protrude until at least the end of the first trimester of pregnancy.
The most common symptom of pregnancy is missing your menstrual period.
So my suggestion at this point would be to wait until you are due for your period, and if it is late, perform a urine pregnancy test according to the package directions. It is too early to experience pregnancy symptoms two days after an act of intercourse, even if your egg was fertilized.
I hope i was able to adequately answer your question today and that this information was helpful.
Best wishes,
Dr. Brown
