Hello madam, from the history you have given, it could be either due to pregnancy
or could be pre menustral symptoms....If your urine test shows two lines, it says you are pregnant...During very early weeks of gestation, the urine test may show faintly positive lines, this could be because of low levels of beta HCG
in early weeks.....i would also suggest you to do an ultrasound
scan in case you have seen two lines even thought it is faintly positive to confirm it is an intrauterine pregnancy. ...hope i was helpful to you. ....
