HELP?!

S.

I made a post about 3-4 days ago because I've been having multiple pregnancy symptoms as well as spotting. I began spotting on the 18th and stopped around the 20th. Today I began spotting again, not enough to fill a pad but more than just a few drops. There are no blood clots but I have been experiencing some uncomfortable cramping.

No, I haven't tested yet because I'm not exactly sure when the best time would be. My period isn't due until next week and I'm not sure if I could be pregnant. Can anybody shed some light based on their experience? Please don't tell me this could be my period because there is no possible way. Nothing like this has ever happened before and my periods are very regular. Never had any ovulation spotting or anything either. Help? Advice?
