So I'm really worried that I might be pregnant I'm 18 years old, I conceived on August 25th (I was ovulating at the time) me and my partner used the pull-out method and my last menstruation day was August 12th and lasted 6 days as usual. I was supposed to get my period today September 13th, but it did not come. On September 1st I started experiencing heartburn, I went to the doctor for it the next morning and they took a pregnancy test to be sure and it was negative. Then I began to notice how much fatigue I was having, though at night I have trouble falling asleep (takes about 2 hours until I fall asleep). Heartburn isn't as bad anymore, but now it has lead to low stomach pains, gas, and severe constipation. Also I'm usually able to eat my first meal of the day, but then come lunch or anything after breakfast I feel like I'm going to puke even if I'm starving, the typical foods I eat don't appeal to me as much and I've been having a craving for salty foods. Also I've been a bit more moody/emotional then usual and have been peeing a bit more then usual. I got 2 pregnancy test (clear blue digital) I took one last night and this morning and both negative. I don't know if this is just me being stressed or what, but I'd like answers or any advice I can get and is it too soon to test? Thank you!
