Hi Just Wondering What Might Be Happening To My Body

Hi just wondering what might be happening to my body , I'll try to shorten a rather long story me n my partner have been having unproyectrd sex for bput 2-3 yrs wit no luck conceving in July / august this yr 2014 we found put we were pregnant - over Joye d and naturally in disbelief I wanted to go for a scan asap at 6-7 weeks pregnant I went for ultrasounds with upsetting results - they couldn't find the fetis in the womb after months of ongoing observation n blood tests etc I was told it was called appregnancy of unknown location and. They naturally let it miscarriage by watching my hormone levels drop . finally in late September it was all over everything else was perfect I was told my cerviex was excellent and to keep trying to conceive once I had a normal menstral cycle : so in October my periods came as normal n we monitored my ovulation days to make sure we had intercourse on my high fertility days : well now were into November and my period was due on 9th - its now the 11th and still no period nor any symptoms of it coming : however its hard not to get excited as soon as my period is late : what I'm wondering is I've now woken up with quiet an itchy vigina - what I think my be thrush - this thrush like symptoms did not appear until 2 days after my period was due - i understand that thrush can delay a period but its not often I get it and there was no thrush leading up to my period day . I'm confused is it possible I'm pregnant ? Or more then likely just delayed period ? Its hard not to get tpp excited too early ! Regards kristina :)
