Sure you could be pregnant...you had unprotected sex...this is sort of how reproduction works.

The question is are you pregnant? We can't know that.

The first symptom of pregnancy is a missed period. You will have to wait to see if your period comes as expected before testing. The symptoms you are experiencing could be attributed to your upcoming period.

Unprotected sex at least 4 days, "more than once a day". What part of getting pregnant do/don't you understand? Of course you could get pregnant.

There are no reliable symptoms of early pregnancy for purposes of guessing, diagnosing or figuring the odds of whether you are pregnant, and trying to figure out what you can't yet know will just make you crazy.

If you miss your period, wait another two weeks, then use first morning urine and take a pregnancy test. Just one test is adequate (some people get neurotic and take a bunch - waste of money). If it's negative and you still think you're pregnant, wait a week and test again. It is important to use first morning urine. Why? Because the pregnancy hormone is most concentrated in the first morning urine.

If you are not trying to get pregnant, go to the doctor, get on birth control and knock it off - high risk behavior. Use condoms, too.

If you're married and settled and financially secure and in a point in your life where you're ready to take care of a child for the next 21 years at least (don't think you're done when the child turns 18 - it just gets more expensive), then still go to the doctor and tell them you are trying to get pregnant. They will provide you advice on nutrition and give you a prescription for prenatal vitamins (not over the counter- these are specific for preventing birth defects). They will tell you what to avoid and so on, and explain things like how they figure out if someone's pregnant, and if they are, how they calculate due dates - it's probably not how you think. If you have any health or genetic concerns, they will address that with you, too.

Oh, and if you're young and possibly rushing to be a parent a little bit (just guessing from the question), please be aware that just in the first year of parenting, costs are easily $10,000 not including the hospital. People think "I'll breast feed and it will be so cheap!" but they are very wrong. New babies need a lot of stuff, and none of it lasts more than a few weeks or months before you have to replace it all. Like those cute little shoes? They will wear them three times and outgrow them.

I'm just covering the bases - for all I know, you've been married for 5 years and have a great job. Or you could be a teenager who wants to grow up to fast - who knows.
