I had 24 hour nausea up until 13 weeks - then bam, all gone. no more fatigue, no nausea, could eat again. Seriously forgot i was pregnant. Nipples remained though and breasts were still tender (although that has now gone). Got subtle reminders at about 16 weeks when i started to feel baby kicking occasionally and i got a little bump, now i still feel normal but have very frequent kicks which certainly reminds me and some horrible ligament pain that is causing a few issues with work. It is a weird feeling to go from being so sick to feeling normal again but this is also normal!
