Pregnant with ovarian cyst ?

Hello.I am 30 years old and have an ovarian cyst.My period is due in a couple of weeks they have not been affected by my cyst.
For the last two wks i have been feeling really nauseus and my breasts are really sore.HPT last wk was negative but i feel just like i did when early pregnant with my only daughter.Im also having the familiar headaches.
I had two normal periods when pregnant with my two youngest and negative prtegnancy results but was pregnant.
I feel pregnant when should i do another test pls?
