My....senses are telling me something

So i know that typically if you’re pregnant you’ll have a dip and than a consistent rise... but has anyone ever had a steady dip and found out they were pregnant? I can smell things I’ve never smelled before and everything smells absolutely horrid. Also haven’t really had an appetite and the things I do have an appetite for are things i don’t typically eat or even like.. just this last week I’ve noticed. I’m moving so life’s been hectic but still no sign of af.
