suddenly feeling ALL the symptoms at 11 weeks!

i’m 11 weeks pregnant and have had the easiest pregnancy so far. my only symptom has been fatigue. but since i turned 11 weeks which was about 3 days ago, i have been feeling horrible! i have nausea, cramps, sharp pains in my back, my fatigue is even worse throughout the day, breasts are super sore, and i’m SO uncomfortable at night, it’s so hard to fall asleep!😩 i thought symptoms were supposed to improve towards the end of first trimester not get worse!!!😔
