I had unprotected sex with a guy. He did not cum inside me. I had just finished my period, like a day or two before having intercourse. After having sex, 2 days later, I got light cramps down my legs and abdominal area. The next day (so 3 days later having after sex) my nipple is really sore. I am scared out of my mind. How early can pregnancy symptoms show? Keep in my mind I am losing my mind and worrying like crazy so is that why I'm getting these symptoms?
Yes, worrying about it can cause symptoms. You can have a false pregnancy, or a hysterical pregnancy. Basically you make yourself have all the symptoms.
The first sign of pregnancy is usually a missed period. Some women do experience "implantation bleeding" about a week before there period was due. It is very light, no pad.
Your symptoms are not specific to pregnancy.
Hope it helps
