Help!

I'm "40 days late" for my period . I'm very irregular and when I do have my period (tmi) it's nothing but blood clots and constant, heavy bleeding from days to even months on end. Well the last week I've been spotting dark red/brown blood once a day . What I mean by that is I wipe and there's the brown/red blood on the toilet paper and maybe two drops on my liner. There are no clots or anything . Has anyone experienced this before?

Yes. We are trying to conceive.
