Hello, and I hope I can help you today. Pregnancy symptoms can vary widely between women and the symptoms that we commonly associate with pregnancy like breast tenderness, bloating, mood changes, and spotting, can also because by hormone imbalances during an irregular menstrual cycle. Furthermore, you should not be able to feel your uterus yourself until at least 15 weeks gestation. The most common sign of pregnancy is a missed menstrual period. So until your period actually is due to arrive and it is late, there is no reason necessarily to expect that your symptoms are caused by pregnancy. If you have no further bleeding around the time that you should ve menstruated, then I would perform a urine pregnancy test that you can purchase over-the-counter for a definite answer. If you are not pregnant, you may be having some hormone imbalances that are resulting in your periods not be consistent every month. The stress of worrying about becoming pregnant can actually cause irregular menstrual cycles. So if you do not desire pregnancy at this time, I recommend you consult with your GYN provider in order to obtain a reliable form of contraception. I hope that I was able to adequately answer your question today, and that this advice was helpful. Best wishes, Dr. Brown
