It could just also be all in your head. Thats happened to me before I thought I was pregnant and I was just so worried about it that my period didnt come. But I suggest you take a preg test just to make sure and have no doubts! Good luck!!

The most noticible symptom is lose of your period, which already have. Some symptoms may not be noticible in some women like


you may feel nausea or queasiness. Some women vomit. ("morning sickness" can happen any time of day --
your breasts swell and may be tender.
Your nipples and the area around the nipples (areola) get darker and broader.
You have to urinate more often.
You feel tired.
You may become constipated and have heartburn (tums may help).
You may have headaches.
You experience mood swings -- feel angry, sad, or happy for no reason.
