Can Someone Help Me

-I Had A Period June 6th, 2019.. I Was Recently Pregnant & Went To The ER On July 12th,2019 For Bleeding

The ER Said I Was Around 4 Weeks Close To 5 Weeks. I Miscarried My Baby & I Was Bleeding July 12th-17th.. Like My Normal Period

My HCG Went Back To 0 Quick. My Fiancée & I Want To Try Again & We Had Unprotected Sex On July 18th.

Today July 21st I’ve Been Feeling Nauseous, Hungry After i Eat, Bloated, Tightness In My Side Stomach With Cramps & Been Having Headaches With Tender Breast. Is This Normal After A Recent Miscarriage After HCG Levels Went Down.?

Thank You❤️
