no PMS or pregnancy symptoms! 11 dpo

Laura
Hi all - I'm in my second month TTC after a miscarriage in March.  With my last pregnancy I had IB but I honestly can't remember if I had any real symptoms before my BFP, although I do think that I had sore and swollen boobs.  This month, immediately after O I had intensely sore nipples but now that's gone away and I have no symptoms even of PMS.  I normally have intensely sore boobs 1-2 weeks before AF.  My temps have remained high and I think I have a triphasic chart, but the lack of any symptoms - feeling totally normal (not even pre-period) - makes me feel that this isn't my month... 
Anyone ever have a BFP without any pregnancy symptoms at all?
