Alright so I have been having pregnancy symptoms. bloating, tingling feeling in my stomach. I had unprotected sex on the 9th, 10th and 11th of August. I didn't realize at the time I was ovulating. I have been having heart burn (not normal for me) and head aches. I wake up at about 1 every morning thinking I'm going to throw up. I took a test late last night and it wad a negative. I'm not sure if I should retest in a couple of weeks or what. this may not even have anything to do with it but I also had a very vivid dream of my first ultrasound and I was having twins...
