I had sex on Aug. 17th, and since then I have had the following signs: weight gain, (recently) stomach changes hard to soft, sick one week. later, over sensitive feelings, and smell at times, very sleepy every day. However, I have had two periods and negative test results. I am on the last day of my second period, and I notice that blue veins are on both of breast? I am so confused please help!

All signs can be many things. if you are having periods then you are not pregnant.. Perhaps you need to see doctor to determine if it is other things
