Dear Friend,
You are having varied symptoms, some of them may be suggesting
pregnancy while others could be due to fatigue or so.
The cardinal symptom of pregnancy is missing a period, which you have not. The other symptoms associated with missing a period in first few months are
frequent urination, nausea &
vomiting and the breast symptoms.
The breast symptoms include dark discolouration of the nipples and areola with increase in the areolar size,
breast engorgement with heaviness and tenderness in the breasts, secretions from the nipples.
I feel, these all symptoms could be due to the stress of the possible pregnancy. The abdomen does not grow before 4 months of pregnancy. Back ache, swollen joints are not symptoms of pregnancy.
Please do not be in the dilemma. Urine pregnancy test and/or
ultrasonography will confirm the diagnosis. If they show negative results, please forget about the possibility of the pregnancy. If still the vague symptoms persist, please report to your doctor.
I hope I have give you proper guidance.
