Back pain

Naylove

My first symptom was lower back pain while sleeping and sitting in a chair, I usually get back pain a week b4 my period when I noticed it a week after my fiancée and I had sex I had a feeling I was pregnant... took a test 6 days b4 my missed period and got a faint line.... I’m 13 weeks now and my boobs still don’t hurt they just feel heavy at times
