Eek. I'm so nervous.

So me and my partner decided we are going to TTC... I'm nervous because we've only been trying fro two months, I came off the pill about 5 months ago... Which should hopefully of been enough time for it to be out my system, I've had regular periods since coming off... I was due on the 8th... And I've had nothing, no pms symptoms, I normally get cramps and sore boobs before I come on always have... This time nothing, all I've been getting is a milky looking discharge which I've not really had before... Ive brought a test but I'm soo so nervous to test... I'm trying to think the worst so I'm not disappointed, because I have PCOS so I've been told from day 1 I may not be able to conceive and my partner has concerns too... Ive brought a tescos own digital test, and I'm nervous incase it won't pick anything up if its an early pregnancy... Shall I still test now?? Ahh 😂😂😂
