discomfort when sitting and sleepy

im really worried it's been two weeks or so.after having sex with my fiance..today is my due for my period but no sign of it. im really having discomfort on sitting..i have to sit in every position i feel comfortable but still im feeling discomfort on my tummy.sometimes i'l just stand up.. and i really really feel sleepy most of the time..and irritated am always angry on some dumb comments, even he hugs me or kiss me im irritated. and i always crave..every 10-30mins..and always tired..[yes,im trying to be have a baby,and im not 16 im 23 on the record.] should i test now? or should i wait a day or three?

i have my period last jan.9 ended last jan.14 or 15., we have sex on jan.26..i have no sign that im having my period today...because before i have my period days before my period i would have brown discharge.but not this week or this past days..and one thing i know when before having my period weeks before i always feel is that my breast really hurts..but no sign.

what do you think girls? should i take the test now?or i should wait a little longer?

i need advice,suggestion etc..but don't make it sound as if your braggin it to me that im notpregnant in CAPSLOCK.my gawd i will surely thank you for that.i need help/advice not braggin me..
