I'm a little confused..I have had very sore breasts for about 2 weeks now, very moody to the point it's driving my bf crazy and lots of lower back pain..my period is 4 days late..this morning I woke up to some light bleeding..my period is never light and I have never had sore breasts due to a period before..I have 2 kids and my books feel like they did when I got pregnant with them. Has anyone else had light bleeding but was pregnant? Ahh so confused.
