Is it too early to believe the test?

So we are on our first round of treatment, I had my EC 13 days ago and had a 5 day transfer 7 days ago!

I've been feeling pretty rubbish had loads of cramps altho no bleed so guess I made myself believe it hadn't worked this time...I'm due to take a Home test on Sunday but I couldn't wait and tested with a clear blue (mainly so I could be prepared for the news and support my hubby) but the test was POSITIVE 1-2 weeks!

Should I take it with a pinch of salt or is there a big chance that it's right and I'm actually pregnant?

Want to take more tests with hubby but don't want him to get excited if it's too early to believe the test...
