2 missed periods, Im loosing my mind!

[TFsMummy]

Hello ladies!
This is a bit of a long one so apologies

I'm 26 and I am a lucky mum of 2 boys, my little hurricanes!
I have been off of the pill since September last year as we decided we would like to try for a third and final child, we aren't putting pressure on it it's waiting to see when it happens it happens sort of thing. I've always had regular periods which I have been tracking since nov last year, up until last month (august) when my period never arrived I'm now 30 days late which means I have now missed 2 periods.. i has lots of symptoms such as- sore nipples, bloating, acne, headaches, tired more than normal and mood swings etc, I have done way too many tests and they have all been BFN, I haven't tested since last week now as I can't bare the thought of another single line and I'm assuming now I've missed 2 periods if I was pregnant it definitely would of shown up by now as with my first 2 pregnancies. The last few days I have been having a lot of cramping and back ache so I thought maybe AF was on its way but I still have absolutely nothing other than creamy/ EWCM (sorry if that's tmi!)
I don't want to waste a doctors time but I'm just as a loss of what to do
Thank you in advance!! Xx

I would recommend going to the GP, could be anything messing up your cycles and they run some tests to see what's going on.
