Dear lady ! From your symptoms I do not consider you to be having any serious kind of health problem. Please go through the following:
1) Because of the long duration of opting for a child by both you and your husband, you may be having some
anxiety and
depression kind of thing. This could be the reason for your mood swings, and forgetfullness due to lack of concentration.
2) Your
chest pain could also be due to your anxiety, as we do not expect a cardiac problem at your age commonly. However, there is no harm in going for a basic cardio vascular check up by a cardiologist.
3) The urinary symptoms could be due to two factors : a) Anxity causes increased frequency of urination which could be the reason in your case. b) your doctor has to exclude
urinary tract infection also by a routine examination of your urine, and also culture sensitivity test if need be.
Back pain could also be related to this. I will also advise you not to hold your urine for long and go to wash room whenever you get the urge.
4) I will advise you not to take a lot of mental stress about your
pregnancy. It is good that both you and your husband are trying for it for several years and this shows how co operative both of you are towards each other. Now a days, ther are many centres specialising in this area of medicine known as
fertility clinics, and they can advise you properly and help to plan out a strategy for a positive outcome of your trial for a child.
5) If your stress is not relieved and your symptoms are increasing , I will suggest you to consult a Psychiatrist/counsellor who can help you out of your stressful mood swings.
I wish both you and your husband a fast and successful increase in your family number. good luck.
