Missed period except for my last pregnancy which was morning sickness, I didn’t realize I’d missed a period until then.
I guess I had always strongly associated the symptom of nausea with migraines. I looked it up and you’re right, while about 90% of migraine sufferers experience nausea, that still leaves a portion that don’t. Mine always started with nausea and vomiting, then unilateral pain that felt like a small fork stabbed in the back of my eye, with the handle extending back into my head. I had sensitivity to light, sound and smell. I also experienced an aura 3 times. I remember the first vividly because it happened in class. I couldn’t get my eyes to focus and it was terrifying, particularly because I had been warned about the nausea and vomiting but not about this and I had no idea how long it would last or how I would get home. It had resolved by the time the class ended, but I was grateful this did not become a common symptom for me. I can drive while vomiting into a drink cup but I’d be stranded if I was stuck somewhere with double-vision. Anyway, as sorry as I am to hear about someone else going through this, it is somewhat of a relief to know someone else has experienced what, for me, was the scariest symptom.
Sorry bostonsavvy for the thread-jacking!
It wasnt planned but I knew it was a possibility. I had suspected before because I was always very irregular and the test had always been nagative. I thought for sure it would be this time too and id have to make a doctor appointment to figure out what was up. I couldnt keep anything down, not even water. Every time I woke up no matter what time of day it was I was instantly nauseas. Cigarette smoke made me really nauseas(im a non-smoker) and any smell that was “different” that I wouldnt normally notice like the smell of dry dog food.(Turns out I had hyperemesis which is severe morning sickness and ended up on an IV). I didnt wanna eat anything especially meat (chicken in particular). I was also super crampy along with other AF symptoms and thought my period was on its way. I couldnt keep my eyes open even if I slept a full night. I took a test and it was positive so fast it was like someone flipped a light on. My jaw hung open for a full five mins and I was so shakey I couldnt stand. Sheer disbeleif lol
terrible metallic taste in my mouth - the only symptom prior to testing. followed a week or two later by fatigue and nausea…yay.
Sore breasts was my only telltale sign, so I took a Dollar Store test and it was positive five days BEFORE my expected period. Pleasantly surprised 
though finding out so early makes for a seemingly very, very long pregnancy!
My last pregnancy I knew before I even tested, b/c I was running to the bathroom all day and even waking up in the night to go.
Nausea and lack of energy - also I’d be flushed periodically… and I’d get hot, I’m always cold. Those were the signs that led to the “maybe you’re pregnant jokes”, the test, and now here I am in my second trimester excited as all heck :razz:
Before a missed period, I have noticed:
tiredness
crankiness
darker nipples
breast tenderness (very pronounced in 1st pregnancy, more subtle in subsequent ones)
occasional, slight nausea (this might have been all in my head, though, before the missed period)
could really smell my deodorant, like it was suddenly a lot more potent-smelling, first thing in the a.m.
About the time of a missed period:
peeing more often
consistent nausea after waking up, and needing to eat crackers or something right away so I wouldn’t feel pukey
more tiredness
