What could it be?

So today at work, I suddey got dizzy and felt a bit faint, I started to get clamy and sweaty fast, took a few minds out to rest in the office and drink some water, still wasn't 100%, but I have this pain (shown in pic) it's like a sharp, constant pain. Bearable but it's letting me know it's there at the same time. Sore to stand sit lye etc, iv had diarrhoea the past two days?

Is it possible that it could be implantion or is it possible it could be another ectopic for me??
