A little concerned..

Melissa • 37, FL Mother of 3 (👧🏻👦🏼👼🏻), rest in peace my sweet baby boy 8/3/17-11/24/22 💔
Yesterday my husband and I had sex in the morning, I also had my first prenatal visit at my OB. About an hour after having sex I had some light spotting, no cramping.. I had a stillbirth in 2010 at 17 weeks so I am already nervous as it is... At the doctors office he checked to make sure my cervix was still closed and it is.. He also mentioned that I could be bleeding for a few more days because my body is cleaning itself out from old blood in my vaginal walls.. He said as long as its not heavy bleeding and cramping worse than period its completly normal.. I am currently 6weeks and 2 days.. Has anyone else have this happen to them??? I go back on June 30th for my 8 week ultrasound.. We already have two kids 10 yrs old girl & 8 yrs old boy!!! Really hoping on my rainbow baby to stick... Im a nervous wreck 😔😔
