"i made Love with my boyfriend Last august 23 this year then i didn't have menstration for one month even for may tiLL august but there no sign that i'm pregnant i had been irreguLar for 2 years i'am pregnant or back to irreguLar"

Take a HPT and find out... or all anyone is doing is guessing. If that's the ONLY time you did it... thats 5 weeks... you should be able to test by now and get a reliable result, pos or negative... assuming you do it first thing in the am the first time you pee.

Ok, you had sex in August. ( sex is not always love, don't confuse the two)

So you have had no period since August 23 ? When was your period in Sept Due ? How late are you ?

It appears it is time to take a pregnancy test, do it with the first urine of the morning.

But yes you could be pregnant or you could just miss this month, or have an infection or have a std, or other issues.

Just no way to tell, first step a test for pregnancy, and if not, trip to doctor for a check up
