For the past two weeks I have been experiencing pregnancy symptoms. I experienced these symptoms; tender/swollen breasts, fatigue, nausea, abdominal bloating, rapid weight gain, and frequent urination. However yesterday I started my period. It was light and I thought that it could be implantation bleeding, but my period is usually light the first day, and today it seems to be a normal period. I'm also on the pill, and have sex frequently with my boyfriend of 3 years. I’m very confused, and wondering what is wrong with me. What do I have that includes all the symptoms that women experience during pregnancy?
