So few a few days Iv had sore boobs, last night they were really really sore, we had sex an I had what I thought come on my period as there seemed to be a Enough blood to use a pad, but when I woke up the next morning and all day today Iv had nothing and havnt used a pad. I am really worried what could this be, has anyone experienced this, im worried it's something really serious , my boobs are still tender also
