First of all just calm down, you are pregnant.
Focus on safe and healthy delivery.
Big belly is not a big issue... Apply coconut oil after delivery regularly.. There won't be any scar.

Are you breastfeeding ?
Do you have Pcod ?
Are you sure it was period discharge and not any miscarriage ?
Consult your gynaec and get a check up done.

Try to rest for sometime,bcz this back pain will be normal in pregnancy,try to support ur back while sitting or doing some work,try to avoid lifting heavy objects nd do somemonth specified exercises,with your gynic acceptance
