4 days late..neg test, coil removed

[Yessy23]

Hi,

Im not sure if im overthinking everything, but just needing some advice.
After a late miscarriage in June '14 me and my partner needed some time to grieve and decided to not ttc again, so I had the copper coil put in August last year. My period have always been clockwork 28 day cycle. The coil didn't change this, only made periods heavier.

On the 17/2/15 I had my coil removed, due to pain during sex as a precaution. I spoke to the doctor and the nurse about risk of pregnancy, id had sex nearly every night the week before (on holiday), they assured me I couldn't become pregnant as long as I used contraception from then on.

Using online calculators between 10/2 and 15/2 is when I ovulated, so before my coil was removed.

Well, my period was due 27/2/15, and nothing. I normally am very emotional, cramp 48 hours before bleeding but nothing. So im now 4 days late. ive taken 3 pregnancy test all negative, used different brands. I don't feel pregnant, last pregnancy I felt sick straight away, very sore breasts, I felt implantation. I knew I was pregnant before I took the test. My only symptoms at the moment are im bloated, slightly sore breast. But I could just be over thinking.

I was just wondering is there any chance im pregnant? Even with negative test? And even with having the coil removed after ovulation? Me and my partner arnt on great terms at the moment, we havnt been for a while, and last year all I wanted was my baby, but now things have changed, he wouldn't be happy if I was.

Im worrying, im sorry. Just any advice would be appreciated.
