Could I be pregnant?

[disneyqueen]

Firstly hi! This is my first post on mumsnet, though I've been on and off over time.
My periods have never been regular - cycles between 28 and 41 days over the last 8 months (been tracking on the clue app). So currently I'm in between those days but I'm really aware of my boobs - they feel hotter and heavier. I got really light headed the other day - but also hadn't drunk much that day. DH and I have been actively trying to get pregnant for 2 months now which is why I'm thinking about it more....
The reason I haven't done a test is that next week I have a friends party (she's off to Australia forever! :( ) and I know there'll be booze there that I will be drinking...so I'm planning on a test the day after.
But my question is 'if' I am pregnant...could I hurt the baby if I did drink next week?

Seriously?? I think you should probably do the responsible thing and take a test and if it's positive not get pissed.
And yes binge drinking could harm your baby, probably not a one off but still could.

You should really test before, why risk possibly harming your unborn child just for a few drinks? testing the day after could b too late, you could of done harm already. If your trying for a baby all drinking, smoking etc should go out the window.
