heeellppp!!

im currently 16 days late, my periods have always been irregular but id usually only be about a week late. i was "supposed to" start october 30th. i had sex with my boyfriend (we're trying for a baby) october 29th, (and november 12th.) i took a test november 12 and november 16th, both negative, so did that just delay my period or could i still be pregnant and its just too early to tell? i don't know when i ovulate or anything because of how irregular i am, all of this is just confusing! we just want a baby!
