My partner and I had frequent unprotected sex during my ovulation time, 3 days after ovulation I started having cramping and slight constipation since then I have been experiencing, dizziness, sickness (no vomit) my breasts have become more tender than usual, I feel really bloated. Also I've noticed I've been having much more discharge (really thick, very stretchy) Even though I haven't missed my period yet I couldn't resist taking a pregnancy test this morning and the result was negative... Has anyone else had the same or similar symptoms and later got a positive?
