considering you've been havin unprotected sex all month, get a hpt. you most of the symptoms but sometimes you're body can trick you but deff. get a test.

You need to take a pregnancy test. Having unprotected sex all month runs a HUGE risk of pregnancy.

Take a test right away so that you can start the prenantal care if you are pregnant.

Please remember that protected sex is a safer way to have sex.

If you are having your period then you are not pregnant. Simple as that. If you have had unprotected sex since your period then you are at risk of being pregnant. Always use protection and know at what times of the month it is best to have sex. The menstrual cycle is about 28 days and your period is at the beginning of the cycle. You are fertile until about the 15th-18th day of the month, but you can never be sure because it can happen after that.

^^ Not every woman has a 28 day cycle and they ovulate at different times so this information is misleading.
To know when you are most fertile during your cycle you would have to be using a method called Fertility Awareness (or Fertility Charting). To use fertility awareness you check your cervical mucous and basal body temperature daily and keep a calendar of different indications that cue you to when you are ovulating and most fertile. Don't forget that sperm can live inside a woman's vagina for up to 72 hours - closing your window for intercourse even more.

The bleeding you're experiencing could be implantation bleeding or just an irregular cycle.
Ash23 is right, having unprotected intercourse so many times throughout the month really ups your chances of being pregnant. You should take a pregnancy test to know for sure if you are pregnant or not.

Visit http://www.plannedparenthood.org to find a clinic near you (by zipcode) many times they offer free pregnancy testing. They also offer a myriad of other resources to help you if you are pregnant. If you aren't pregnant, they can help you with birth control options and set you up with annual exams to be sure everything down there is OK. Some clinics go by your finances when they charge you, so you may be eligible for free services.

I said ABOUT 28 days and ABOUT the 15th-18th day, but anyway I definitely agree that using fertitlity awareness is a good idea.

well there are a lot of ways to know you are pregnant...like missing your periot, feeling bloated, a need to sleep more often, cramping, need 2 go to the bathroom more often but all of these answers cant say for sure... the best is to take a home test or see a dr.

I'm on the pill (for over 7 years) and all of a sudden I started having weird periods lately. Every other month I have a very light period (spotting) and then the next month its very heavy. Two months ago my period only spotted for about a day and then this month it got pretty heavy on the 2nd day and now its very light again. Should I be concerned about pregnancy? I'm getting my period each month on the exact day that I'm supposed to so I have no idea what's going on. Help!!
