HELP?! opinions please!

I've had heavy heavy EWCM for the past 2-3 days. TMI but before this I was kind of dry. I haven't had a period since April 2016 (before I conceived my second son, who is know turning 1 in January). Does the CM mean I'm fertile again or pregnant? When would you test? I don't want to test all of the time but I don't even know where to start?? Any ideas/opinions? I've tested every other week prior to now. I just have this constant fear that I'm pregnant again and I don't know it. So I don't want to test everyday. Is weekly a good plan? I tested last Friday (BFN).
