Should I test again ?

I had an ep in march 2014 before that me and oh we're trying for 12 months. After I had my left tube removed we waited 3months then started trying again. I have 35day cycle this time I had my af 24 August so I should have had my next cycle 28th September  but Instead a week before my af was due due i had a very light bleed one day then spotting I only wore a liner to keep fresh but I didn't need it that's how light it was. I tested on the 27th a day before my af and got a negative :(  I want to test again but don't want to be sad again. But still no af and near my boobs were my arm pits are hurt and I feel like there's summit irritating my left hip on inside sounds daft it's not painful just there. I want to test but I don't :(
