dizziness

Is it normal to have dizziness? I ask because I've been pregnant before but have never felt this I am 5 weeks pregnant and this morning soon as I woke up I felt very dizzy I had to sit it did pass after like 20 minutes though 
Idk if I got up too fast because usually I wake up and lay on my phone for about 30 to 40 minutes and then get up but today I woke up late to get my son ready for school so as soon as i saw what time it was i got up quick
So far after that I haven't had it anymore
