I had some really early signs with this pregnancy. 2dpo I had a "full" feeling in my lower abdomen area & was very tender there too. Had been DTD heaps & I just went completely off it, was quite strange!! Also had cramping like pains, sore nipples & no appetite. This all went on until 6dpo. From 7dpo to 11 dpo I was beyond exhausted & my legs ached all day. 12dpo I had an implantation bleed which is when I tested. When I got the BFP it was not a surprise at all, I had been telling DH for days I was pregnant. Maybe next time he'll believe me!!
By the way, the only reason I can remember all this is because I was keeping a diary of all my symptoms to work out my cycle. Maybe if I hadn't been paying so much attention to my body I wouldn't have noticed any of it!!
I hope you get your BFP
