I had sex on the 9th and it is now the 15th. I know it usually takes up to two works or after your missed period to have pregnancy symptoms, but I have just simply felt pregnant and have quite of few signs is it possible that I am already having pregnancy symptoms or could it be something else?

Most women probably wouldn't notice by then, but is possible to feel pregnancy symptoms if you conceived 6 days ago.

Typically, implantation of a fertilized egg happens 7 - 10 days after ovulation, but six days is still close to that window.

That being said, early pregnancy signs can be identical to PMS. Wait until you are within a day or two of your expected period before you take a HPT.

I would do pregnancy test. But I felt pregnant very early before I had a test.
