Weird smells at 10+3

Is there anyone here dealing with foul smells out of nowhere that'll not let you even sleep? My first pregnancy I had 0 morning sickness, no crazy cravings. NOTHING! Since last Wednesday I keep consistently smelling weird and disgusting smells (like a sewer) before going to sleep. On one occasion I was already sleeping and out of the blue the smell hit me, woke me up and it was difficult to sleep again. We checked EVERYTHING inside the room, inside the house, outside the house, cat area, you name it. There is NOTHING that could possibly trigger that smell. Is it the hormones? Am I going crazy?
