We had unprotected sex within 2 weeks everyday, but today I've got my period :(!! So, what's wrong ?

How long have you been trying? It takes the average healthy couple up to a year or more of actively trying before actually conceiving.

Be patient. It can take completely healthy people 6 months to a year. Even if you time having sex perfectly during your ovulation it's not a 100% done deal. There are a few methods of tracking your ovulation. Ovulation Calculator: Free Ovulation Calendar, Online Pregnancy Test, and Fertility Charting (http://Www.ovulation-calculator.com) is a good source. In the mean time try being as healthy as you can; no drinking or smoking, drink lots of water, eat healthy and start taking prenatal vitamins. Good luck!

If you are having that much unprotected sex and not getting pregnant its either a sperm or egg problem... see a fertility expert

First how old are you, I ask since to expect pregnancy first month is somewhat?
