i had unprotected sex 3 weeks ago, 2 or 3 days after my period. a week after i spotted & also felt sick like nausea which lasted a day or two. this is now week 3 & since monday my boobs have been sore & i've never had sore boobs ever. i've been peeing non stop ; headaches & constantly tired. im due for my period this week or next but i just feel pregnant if that makes sense lol. i took a test last night & it was negative also went to the doctor today & he told me not to bother cause its too early to detect ; so could i be pregnant? or should i just wait & see if i get my period? before i think that far ahead? x
