Yesterday I had some twinges in my lower abdomen towards the right side that somewhat felt like a muscle spasm. Later on in the day I had some very light cramping on that side. All morning today I still had some light cramping on that side and then later on in the afternoon I had some sharp pains in my ovary that lasted maybe a minute. When I got pregnant with my son I remember having a sharp pain like that when implantation happened. So Im thinking that the pains that I had may have been implantation. Starting yesterday my breasts have been really sore and I have been having more frequent urination. While I was having the cramping I also was experiencing some back pain too. Now both the cramping and back pain are gone. How soon after implantation if that is actually what it was can I take a pregnancy test?
