It doesn't appear you timed intercourse well enough for PG. Birth control methods fail however. Best of luck to you however it turns out for you this month.
i've also noticed heart palpitations...is that a symptom associated with pregnancy?? i hadn't thought of that as a cause..i quit drinking caffeine because i thought it was from that, but they haven't stopped
heart palpitations caused by caffeine intake can take months to stop. I have that same problem as well and it is very irritating. I have not heard of heart palpitations being assosiated with pg, but it really does not look like you would have been able to concieve this month unless there were other times that you bd'd that are not on this chart.
