I am 19 yrs old. I was in a doubt that I am pregnant since I didn't get my periods for so many days, I took 4 pregnancy tests and 4 are negative. After 23 days delay I got my periods. But I still had a doubt that I may be pregnant because I read an article that during the first 2 months of pregnancy, the pregnant lady could have bleeding. But my bleeding was same like periods and I got them for 4 days. I feel that my stomach is slightly bigger ( I don't do any exercises). I feel very slight pain in my stomach. I don't have any pregnancy symptoms. AND IF I am pregnant it is a 12 week pregnancy. Can I still be pregnant? Or is it just my feeling that I am pregnant?

Most important question: did you have sex, and when did you have sex?

If your periods are as normal, and you've done four pregnancy tests at the right time, I think it's safe to say you are not pregnant.

It's possible to be pregnant and have a little spotting around the time you'd expect a period, but you don't have a normal period when you are pregnant.

I had sex on November 19th and it is an unprotected sex but he took IT out before he came. I took 2 pregnancy tests after 10 days delay of my periods and another 2 after 16 days delay of my periods. And all are negative. I got my periods after 23 days delay and they are normal as my regular periods. But still I had a doubt and I want to clarify it.

You had four negative tests and your period. While pulling out is not a reliable method of contraception, it does reduce the odds of pregnancy. So it's a safe bet you are not pregnant. If you really thought you were pregnant, it would now be worth booking an ultrasound at your local hospital, because a baby would now show up clearly on it.
