My DH and I are ttc and the week before ovulation we had sex everyday including 2 days after. I had some cramping around 3dpo and on 7 dpo. Since then no cramps. On 10 dpo I noticed a light pink smear on tissue when I wiped, but only once. Have not seen any trace since then. It's now 12 dpo and no cramps, no sign of period coming, only tender nipples ever so often, but they return to normal within a few minutes. Can these be signs of pregnancy? Should I be testing yet?
