First day of last period was 12/8/11. Had unprotected sex on Dec. 16th & 17th. Haven't been on because in over 6 months. Age 34. Two children, already. AF due 1/4. One week prior to when AF was due, had frequent urination, heartburn, runny nose, tingling in breasts, slight nausea, forgetfulness, dizziness, increased appetite, fatigue. Tested at 7 & 10 dpo. Both negative. On 1/4, had light bleeding for 2 days. Figured it was period. 2-3 days typical period for me. However, still feel pregnant. I also have insomnia, gas, feeling of lower abdominal fullness, food cravings (deviled eggs), fatigue. Wondering if I could be pregnant after all. Thinking of taking hpt again. Is it possible my "period" was actually implantation bleeding?

*Birth control, not because (stupid autocorrect)

Some people have implantation at the time they would have their period. But it is normally brown or pink spotting. Since its been 2 weeks since that test again. It is very possible you're pregnant.
