With my first and third pregnancy I had NO symptoms at all. It wasnt until I was reminded that I hadnt had my period for a while that I tested and had BFPs. In both cases I was about 5-6 weeks before I realised. There was no sore bbs, no frequent pee etc. This time round I have had a tiny bit of nausea, but still no frequent peeing as of yet.
Good luck :-)
