yes my boobs got swollen and tender early on in 2nd pregnancy
however I had problems conceiving 2nd time round and I have to say that every month I would notice the same swelling / tenderness and convince myself I was preggers only to be disappointed so I wouldn't go by any physical sign other than your pee turning a stick blue IYSWIM
I found it heartbreaking the psychosomatic symptoms I went through just before periods started
I would say stop flashing yerself tbh
