Hmmm...could i be this time?

so okay i am 6dpo today and well being sooo impatient i took an HPT yesterday and it had a faint line but ONLY after like 30 mins later when it was dried up so im chalking that up to an evap line. oh well..its toooooo early for that seeing as though i took it on 5dpo lol. well anyways...my left nipple has been leaking off and on..my bb's are sore and tingly as can be...ever since like 3dpo sooo...is that a sign? and also, im more tired than usual. alot of headaches, crampy and twingy low abdomen. other than that, nothing. does it sound like i am? i mean we have BD'ed every other day leading up to 3 days before ovulation then 3 days before we did it every day then every other day after that so im hoping and praying! i think i had a chemical pregnancy or early miscarriage last month cuz i felt pregnant and had lots of faint pos. hpts then got my period 4 days early which never happens!!! oh yeah and i also have heartburn ALOT!!! and very hungry :)
