I got pregnant last July, unfortunately had a misscarriage at 9 weeks. I had symptoms 1 week after having sex that time. I'm one week after having sex and I'm having what I think could be pregnancy symptoms. Tender breasts, dizzy, sensitive to smell, cramps, emotional and extremely tired. I was tracking my ovulation with clear blue ovulation sticks I had many days with flashing smiley face but no solid smiley faces. Could I be pregnant?
