my last period started v. late at night on 7th July. There is a poss. that I could be pregnant. I have 3 others and with all of them I got a BFP before my period was due. This time I feel pregnant, have a metallic taste in my mouth, sore boobs, v. tired in a preg. way, but I tested today and it is negative. My cycle is usually 28days but now and again it is up to 35 days - just every 2 or 3 months or so. Now obviously my period could just be v. overdue, but feel so weird and last 3 months my period has been 28 days textbook like. I think a preg. test would have shown a BFP by now if I was pregnant. But given the slight irregularity ogof them am I testing too early??
