TTC- early pregnancy signs

Hello everyone I have been off bc for 5months now lately I've been on a 27 day cycles and monitoring my ovulation dates. my husband and I have had sex 5 times during my fertility period and lately I have been very nausea, tired, expercincing rapid heart beats and just yesterday had a lot of white creamy discharge with no smell or anything my period is due on the 17/8. Has this every happened to anyone or is this just normal menstrual since getting off bc or could these be early pregency signs ??
