So its 5dpo for me as of today and this is this 1st month i actually successfully ttc'd. Meaning he finished inside me twice during my fertile period. So sperm were swimming in me before and during ovulation. ( i used an opk so i knw i ovulated, had the cramps also). Anywho i have been trying not to think about the fact that for the first time ever i REALLY could actually be pregnant. But yesterday at 4dpo i got tired asf out the blue around 1pm and ended up taking a nap. And When i laid on my stomach my breast were a lil pinchy on the sides. I thought it was strange but Was too tired to think about it. Moving on to last night. I get ready to go to sleep ..and when i laid down my breast were deffinately sore this time not just pinchy. Moving on to today 5dpo.. and now i can feel they are sore ..rather i lay on them or not. When did yo sore boobs kick in when you were/or if your pregnant.
