My breasts feel different. They full fuller and tingle and sometimes my nipples hurt. Not like all the time, I just get sharp pains in my nipples every once in awhile. I don't know if that's a sign, I'm only 4dpo. It might just be in my head 😓 I also have been cramping since the day we had sex, the day I ovulated but I also know you won't have implantation until almost a week after. I'm just wondering, have anyone else felt this way?
