Spotting turned into loss

Well I was SO excited on Thursday  to post my chart on here & announce my BFP on Fridayafyer 5 + tests!! After 8 months of trying this was such a happy time & a relief.. Well this weekend I experienced light spotting- mostly brown and after reading and reading on here I had calmed myself down as it's pretty normal.  Well brown turned pink yesterday (Easter morning) so I took another Frer test yesterday and it was definitely more faint.  This AM I got bright red blood and my digital that said positive 1-2 weeks now read the dreaded "not pregnant". I called my drs office and a blood test confirmed what I feared, that I had lost my lil bean at only 5 weeks:( I'm heartbroken but I know it'll be okay. Just wanted to share this in case others have had the same thing.. When it happens this early.. I'm not sure why? Or if I'll ever know??  I have a dr appt next Wed to look at maybe doing some tests and see if there is anything preventing us from getting/staying pregnant... So now I'm ready for a January baby!! Good luck to all of you!
