Hi everyone I really need help om struggling here to understand whats happening to my body.

I've been a week late for my period and began feeling nausea, tired , my breast are quite sore as well my sense of smell and taste has increased.

Today on the 7th day I'm late I started to have brown discharge, then began to bleed lightly. I've still been bleeding or spotting its not dark red it a mixture of pink and light red.

I've started cramping in my lower back and stomach, the pain was on and off for 4 hours. I now have no pain but have no idea what to do next ?

Can anyone give any advice on what I do next
