Need advice

So I bought three of the 6 days sooner first response test and as of tomorrow my period is due is 6 days I am always regular. I was wondering if I should test in the morning with FMU or wait a few days? And if anybody has taken a first response 6 days before their period was due and got a BFP please let me know! With my daughter I got a clear positive with this test at 7 days before my period was due but I have been taking dollar store cheapies and they all say BFN... I’m currently 11 DPO. Any help is greatly appreciated! Thanks again!(:
