Seems like Implant Spotting to me, but I've never seen examples of O spotting or had either, so don't listen to me this time around.
BOOBIES!! Yep, mine are showing yet another symptom. First there was the soreness, which had been non-stop since about what FF says was 16dpo. Then there were the roadmap veins and the tingly nips, which also haven't gone away. NOW the fullness I thought I was imagining has turned into full-blown engorgement. My bb's are no longer saggy and jiggly, they are firm and full and about a cup size larger, meaning I can't wear most of my clothes and ALL of my bras are too tight and uncomfortable (with muffin top bb's hanging out). WTH??????
