AF was due 23 August and she hasn't showed up. Positive OPK on cycle day 19 and 20 which was 13th/14th August so currently around 13dpo. Trying for baby#2. I had a look back at my diary for my LO and my cycle was different but counted my dpo for positive test to 16 dpo. I have sore tingly boobs up into my arm pits and I'm tired, with hot flushes. I haven't really thought about getting pregnant until AF didn't show and I'm not stressed. I have had 2 negative tests with Amazon cheapies. Has anyone else had this and then gone on to have the BFP later on.
