So I ovulated on October 13th, and me and my boyfriend had sex on the same day. I started my "period" on the 29th of October, and it was 3 days late. That "period" only lasted for 3 days though and was lighter than usual, when they're usually 5 days long. A week before I started, I was having cold symptoms and was a little light headed. Now it's the 17th of November, and I'm occasionally sick to my stomach, I've been light headed still, and I'm having weird cramping in my feet at night. I took an hpt on the 29th of October and it was negative. Can anyone tell me if this has happened to them, or give me any kind of information.
