Congratuations ah! If you are not sure whether you are pregnant or not, you can try to buy the pregnancy tester again. If it is positive again, then very likely you are pregnant. And if you want to check go to the doctor, they can usually confirm very early during pregnancy. One of my friend found out she is pregnant when she was at only 5 weeks.
My baby was born in June 07. I am pregnant for 2 months now again but doctor just confirmed my miscarriage. Doctor advised me to do an operation. I worried a lot. Not happy.
