Hello mommies

I had a miscarriage 4 weeks ago, OB told me to try anytime I wanted to. After I stopped bleeding, (3weeke ago) we no longer b usuing protection. My period supposed to come in 3 days I’m hoping it doesn’t. What y’all think? Do you guys think im pregnant? Last time it only took us a month and I was already pregnant but unfortunately my baby didn’t make it lost it at 6 weeks. And I forgot to mention I already have a son who’s 5 years old so I was shocked about my miscarriage. I don’t understand why until now.
