Am I out?

Hi guys, I'm new around here and also new to the lingo... so let's give this a go! 

This is our first month TTC and like everyone else im obsessing over this happening straight away! I came off the pill 2 months ago and I had my withdrawal bleed 4th april. we did the 'deed' alot this month over my fertile window. About a week ago I have period pains for 3 days, dizziness and sore nipples. I have done 2 HPT clearblue early detection (due in 2 days) and both are BFN. Today I have period pains and nausea and my mood swings have been off the chart the past two days. 

Am I out for this month? Or is it still possible to be pregnant but too early for the HPT to show? 

I'm hoping to find a TTC buddy who is on the same cycle.

Thanks in advance lovelies!
