Dear user, welcome to healthcare magic.
We cannot suggest pregnancy
by the symptoms you mention because they are non specific.
You can have a blood test
now or a home urine test after one week.
If the test is positive, start taking Folic acid
supplements and have a visit to your doctor to do an ultrasound
to confirm a healthy intrauterine pregnancy and exclude ectopic.
I wish you get pregnant soon. Good luck.
Dr. Ahmed Bahaa.
