vaginapagina | Nipple pain, sore breasts

I looked through memories somewhat but only found things about lumps and leakage and bras.

For the past 3 days or so my breasts have been very sore. Not so sore it hurts to put on a bra, but sore enough when they're touched, especialy my nipples. Is this something I should be concerned about? Is it part of a normal menstural cycle?

I've been on different types of pills for 5 years, but I stopped taking them after this last pack because A) I ran out and the company takes forever to ship them to me (stupid insurance) and B) I had my wisdom teeth out and am still on antibiotics and didn't want to "waste pills" So I guess this is my first "normal" cycle in a while and I don't remember what they're supposed to be like.

Any input would be great, thanks!
