am i pregnant

so i started barely having sex with a guy on saturday the 20th (i ovulate this friday the 26th) and he didn’t really even get completely it in me before i got afraid bc he didn’t have a condom. yet when i got home, i saw a white creamy discharge in my underwear that almost looked like cum and it kinda smelt salty too. i took a really hot shower that night and made sure to wash really well. i took a Take Action pill the next day just to be sure of the situation. that same day on sunday i noticed the discharge again, and once again yesterday. then today i saw it again with a very slight light pink tint in a part of it. i have been really moody since then (such as one minute i’m tired, next i’m grouchy, then i’m super cheerful and laughing..i also haven’t been really tired or anything either), and have been cramping in my lower abdomen and back. i’m rarely nauseous and don’t have headaches. i’ve also felt kind of booted but that has gotten better. however the day before i took a bleach home test and it fizzed and soon did nothing giving a negative result. but yesterday morning i did it again and it foamed for a little bit and after a minute or two fizzled out and again did nothing. is there anyway i could be pregnant? and i know there’s always a chance but does it seem like i am? i get my period on the 10th of February about 2 1/2 weeks from now (my cycle is really irregular as well) and am really anxious and stressed about this bc i can’t tell my parents. so does anyone know anything about this?
