Like back pain, at least 2-3 times go to loo with in hour and my stomach is little burning and streching full so suggest me what will I do ? Doc say take medicine for regular period sggest me good things bcoz I want to concev now.

So am I understand you are nearly two weeks late? The symptoms you described are symptoms of the last trimester, which you couldn't be in. Why didn't you ask your doctor when you were there? When was that visit?

Every pregnancy is different. You can have different signs then another woman and you can different signs from your own pregnancies. If you are very regular with your periods and you are late then yes it is a possibility that you are pregnant. You can get pregnant when ever your body releases the egg. Implantation can happen between 5-12 days after ovulation which is when your expected period is due. You could very well be pregnant. I would make my way down to the store and get some prenatal vitamins with folic acid just to make sure that if you are pregnant your baby is getting the nutrients it needs.
