Could I be pregnant?

I have the implant (had it for about 9 months)

My boyfriend has always came in me, very rarely pulls out.

We had sex about over 2 weeks ago.

These last 3 days I've had slight cramps but they're different from period cramps and 'needing a poo' cramps.

Also I've been peeing none stop.

Is there a chance I could be pregnant?

I did a test just over a week ago so it was probably too early (it was negative)

What do you girls think? x

*EDIT* - I don't have periods anymore due to the implant, so I waiting for it to come is out the question x
