Symptoms stopped...?

So when I first found out at four weeks, 4 days and up until 5 weeks on the nose, I was feeling bloated, gassy and a bit crampy. I was also urinating every half hour!!. I knew I was pregnant... Now it's exactly five weeks and suddenly, I feel nothing. I don't have to pee every two seconds... No gassyness, no bloatedness... My husband is trying to tell me that it's probably just a transitioning phase... I have no spotting or bleeding and this is my first pregnancy and I'm 27 years old... Has anyone else experienced the same thing I'm going through? Trying not to be nervous!
