Hi i know exactly how you feel. Sometimes it's cruel but a lot of pregnancy symptoms are the same as period symptoms. They usually say it's about 2 weeks after conception that you start to get symptoms but not everyone is the same.

My partner and i have been trying to have a baby and i was convinced this month that i would be pregnant but unfortunately 2 early tests negative and 2 days late period i eventually came on.

The chances of pregnancy are likely, if you are planning a child the hardest part is trying to predict when your most fertile days are. I think it might be better for you if you just wait until you miss you period as really thats the first most for most sign of pregnancy and take it from there. Otherwise if you want test up to 4 days early then you need to remember to use the morning urine (I forgot that i mine and tested in the middle of the day) but it also depends on the amount of HCG in your urine as home pregnancy tests aren't that sensitive.

i agree with the message above. maybe if you arent pregnant this go around, have sex on the 13th, 14th, and 15th of your cycle. maybe even the 12th =p.
