Is it possible?!

Currently trying to get pregnant. I had a mc last may at 12 weeks. I've had irr periods for a few years now since getting off bc. the first time i found out i was pregnant i had diarrhea for two weeks until i took a test. Last week i started having diarrhea again like the last time till now, only in the mornings. i recently had my period aug 4-8. but before my period i had sx july 5, 27 & aug 1 & 8. Could I be possibly pregnant? or is it too early to tell? Anything helps! Thank you!
