I am not certain if your pain you are describing is breast or lower abdominal pain. Implantation generally is not painful or crampy - remember that at the time of implantation the embryo is microscopic. As far as determining whether or not you are pregnant, only time will tell - if you are a couple of days late for your expected period, you should do a pregnancy test. If your pain persists, you should follow up with your doctor - mild crampiness midcycle at ovulation is pretty common, but it is not common to be kept awake and need pain pills for pain. That should be looked into if it persists.
it's both . thank you for response
