Hello
Thanks for writing to us with your health concern.
As you are due to start your period in two days, yes, it is too early to take a home
pregnancy test.
All the symptoms you describe do fit in with those of early pregnancy.
However, they also equally well fit in with pre menstrual symptoms !
Reading too much into the non specific symptoms of pregnancy is unwise.
Best is to rely on a positive pregnancy test, that confirms that you indeed ARE pregnant.
The best time to take it, so that you are in no doubt, is when you have missed your period well by 3 - 5 days.
As you are having
PCOS, if you are having irregular cycles, wait out the length of your longest cycle duration, and then take the test.
All the best.
