Is it normal to feel dizziness and be tired after a week of getting less sleep and exerting physical energy

Anonymous
This past weekend I had a cheer competition that I had to get up early for and was there all day for two days. I had to fill in for this girl on a different team and compete with my own team which I'm not used to. So this past week I've been going to practice everyday and its been very tiring and I've been getting less sleep than I'm used to. Today I slept in and when I came home I took a nap.

however I'm wondering if I may be pregnant. About two weeks ago my boyfriend and I were playing around and he put it in for about 20 secs but he wasn't wet when he went in or came out. That's the only activity we've been involved in. I got car sick in traffic, but I've always gotten car sick easily. The other time I got dizzy I was exhausted and hot and stood up really fast and started chasing my dog. Other than these things nothing has happened and I've experienced all these things many times before. Also I had my period in the beginning of December and in the last week that crossed over into January so I don't know when to expect my next period.
