pregnant?

Hey guys so me and my fiancé had unprotected sex through the 20th-27th.

We were on vacation and we didn't think to pack condoms (idk why). So I didn't stress thinking we probably wouldn't have much sex anyways because we would be so tired from exploring all day. Well I just happened to be a complete horn dog the WHOLE time not realizing it was my "fertile week" until I got home 🤦🏼‍♀️.. so my fertile week was literally those exact days.. so I'm one of those people who freak out over "nothing" but I'm really starting to think this is over nothing. 

So I've been tracking like a maniac and have not had implantation bleeding... BUT.. I have been experiencing sore breast/cramping (which i experience that before period as well).. have been experiencing extreme nausea in the mornings (like I need to eat something or I'm going to throw up EVERYWHERE) and just extreme fatigue.. I'm supposed to start my period today/tomorrow (say this because if I don't start the day I'm supposed to I LITERALLY start the next day.. I'm never late) 

Soo here is what really just makes me want to rip my hair out!! I'm having a crap time of discharge!! No not bloody discharge.. none in it at all but just plan white colored discharge.. so I pretty much need yalls opinions on what you guys think! 

Don't want any judgmental comments. Girls can be mean I get that but this site is supposed to build people up not break them down! Gonna give you a little background of myself so people don't think I'm 13 with a bf who doesn't know what I'm talking about... I'm 21 with a fiancé and we have been together 3 years ❤ we are both financially stable enough to have kids and have our own place BUT he literally works 30+ hours a WEEK and I'm going through nursing school so no matter how badly we want a kid right now, it's just not the right time!! SO thank you guys in advance and please comment! Need some advice before I faint! Y'all rock! 🤘🏼
