Falling during pregnancy...

I fell today while it was raining outside and my sandal was wet. I did not hit my belly at all. I sure did scrape the hell out of my knee though and I broke my big toe nail. 😔 My doctor said as long as there is no blood or I’m not in pain, I should be fine. That if something were to be wrong I would immediately feel some type of abdominal pain or cramps. I have a regular appointment this Friday. I’m 8 weeks along. I’m just worried. 😰
