when should i test

[confused-mom]

when should i be able to take a pregnancy test and it be accurate. i think i might be but i am not sure. i am what i consider a 3 to 4 days late but i still i can't be sure. my periods have been messed up since i got off BC 2 years ago. but usually i start between day 27 to day 30, today is day 30. usually it starts around day 27 or 28. i have some symptom but then again i can't be sure because my hormones have been messed up since i got off BC. i have had some of the same symptoms in the past and have not be pregnant. i have been experiencing hot flashes, dizzy spells, headaches, and  really fatigue. my boobs have been a little sore but that could be because i am fixing to start.

i have never found out i was pregnant by the pregnancy test i have always went to the doc to find out.

oh yea one more thing sorry if tmi, but i have been noticing a discharge, clear on my panties i noticed it sunday. and the symptom i have been experiencing started Thursday which would have been day 26.

so can any of you ladies please help me. i got the test i just don't know when to take it. i only got one so i want to make sure i take it around the right time because you know them test are expensive.

thanks ladies
