Okay soo me and my fiancé have been ttc for about 2 months now and well my period is due on the 3rd of January which is 7 days away. Well my green window or ovulation was the 17 to the 22 of December. We had sex many time thia month but on on my 8% day and my 27% day of getting pregnant tjose were the highest. If he did get me pregnant in that window. How soon would i be able to test. I have been very nauseous and my breast are very sore and i have been eating alot more but then getting sick or heart burn. Is it to early to test?
