I hope I have the right group to ask this question... 
My ovulation date was on the 7th and my husband and I have been ttc for our first. I know it's too soon to tell but my breasts have been really sore the past couple days and I'm just wondering if that's common this soon in pregnancy? I hope it's not my period :/
