Just a rant

My period is late. I took a pregnancy test the day my period was due and it was negative. I haven't taken one since because I want to wait a couple days to see if AF shows up. if she doesn't show up by tomorrow morning im going to take another test. My period can fluctuate days so this isn't uncommon for me... but every little symptom I have I always dwell on it and think "Oh I could be pregnant" like for example... I get off and on cramps in my back and also what feels like pinching cramps mixed with light period cramps. That's probably just AF coming but I always second guess it. I have a stuffed up nose and I'm like oh some ladies get that when they are pregnant! but there is also a cold going around so it's probably that. I feel nauseas at times and it comes in waves. I'm not throwing up or anything but can have a sore stomach and diarrhea..There is a stomach bug going around so again it's probably that. I've been getting intense headaches... again could be a sickness I'm tired, I came home after work and immediately passed out on the couch and slept until my boyfriend came home at midnight and then went upstairs and fell back asleep. I've been wanting naps during the day. could be also the fact I'm not feeling well. I'm super thirsty all the time. I don't have an explanation for that. I can't stand the smell of onions and I can smell them from a mile away. My sense of smell has heitened... could be the flu. and finally I do find myself having to pee more but I think that has to do with me drinking lots of water because I feel thirsty all the time. I always take these and think they are pregnancy symptoms and convince myself I'm pregnant... when I'm probably not.
