So I have been having a lot of pregnancy symptoms in the past three weeks such as nausea, headaches, extremely tired, always hungry, mood swings, and I've gained weight too. However, I just got my period yesterday but it is very bright red and lighter than usual mixed with some clear mucus.. sorry for the TMI. I took two pregnancy tests awhile back and both said negative. Also, I'm seeing more montgomery glands as well. Any thoughts? Could I be pregnant?
