I have symptoms of period for almost two weeks already but it doesn't come yet. Should I concern about having a pregnancy test now? But well, I had sex last time on 28th of August and I had period on 29th of August - 1st of September, and I never have my period yet since then.

Normally, my period doesn't come as normal as another woman except when I take the birth control. Sometimes it comes a week too late or sometimes even a month too late, when I asked my doctor, she always said that because of my stressful and my cycle. Any ideas about this? And my another curiousity is if there a way to change this ?

Help! Thanks!

If you had sex then yes, it's possible to be pregnant.

You said you had a period after having sex the last time, still, it could be, anything is possible.

The only way to know for sure is to take an hpt, use first morning urine as it's more accurate.

As for changing your cycle, some women are never regular without medication. If you're concerned then talk to your doctor.

Good luck.
