I'm 26, sexualy active, had unprotected sex with my partner, my cycle is 28 normally days, especially in the summer when it's also quite light. Now my period was 2 days late, i've been experiencing very strange feelings, like bloated lower abdomen, sore breast, enlarged breast, fatigue, hypersensitivity to odours, mood swinging, heartburn. i'm a very sporty person (i do any sport activity normally during my period without experiencing pain or anything), but these days my body just didn't feel like my body at all, i was literally dragging myself and took a pregnancy test and turned out negative, and then my period came but it's really different than normal, very dark and dense with lot of blood clots that i usually don't have. i also have some back pain, teirdness.
