6days missed period, now bright red bleeding. Cramps, back pain, weeing a lot more, breast soreness, tired craving charcoal & salt. Hpt neg, am I pregnant?

Not likely. If you pregnancy test was done correctly and was negative 6 days after a missed period, you are not likely to be pregnant. You may have other hormonal issues that are causing the missed period and other symptoms. If you miss more than two periods, please see your doctor.
