Hi I am 10 days late have pcos but never late. Had the merena coil removed day 5 of my period (16/12/15) was intimate with my partner on day 14/15 then had a 2 day period very light (highly unusual) on the 6th Jan to the 7th Jan, I have had no period since!!! I never miss one I can go early but never late!!! I have done 2 tests both negative!!! And now freaking out!!! I'm peeing more, tingly boobs and strange taste in my mouth (metalic) and extremely hormonal!? Am I pregnant? Advice please thanks
