Unsure if worth testing or not

Rachel
New to ttc, had what everyone describes as spotting for 3 days when I went the loo and one clot only when the loo. This is my 4th day late. I am currently on holiday and didn't bring any tests is it worth finding a chemist and testing or am I being over hopefully been as I had one clot (spotting info says should have non). 2nd month ttc, was in the pill.
