Hi, I am 40, normal, healthy (except for hypo thyroid which is being treated). I ve always had regular periods, but had sex in June with a condom and the had a late period a few days later. Then 21 days late. I feel queasy, lightheaded, sensitive to smell, moody, tired. Negative urine test done a week ago. My stomach/ breast are getting bigger despite exercise. Saw very faint pink yesterday when I wiped, but disappeared and I saw it again today following mild cramping. Please help!!!!
