question ladies

Just a little history I had a CP back on May 12th and I bled 3 days like a normal period and my doctor told me it was safe to try to conceive again...so me and my husband has been BD a lot not really watching when I am ovulating...the past 2 days I have been feeling really nauseous in the morning and really bloated. Now I have a lot of salvia in my mouth and it is making me feel like I need to spit, I'm in my TWW and I am currently on 5dpo...has anyone ever experience this, it could it be possible I'm pregnant again?
