I'm 9 weeks and 4 days. My husband and I had inter course last night. I didn't bleed then, so I thought I was in the clear. Then today, I went to use the restroom and I saw brown blood on my underwear. Then, when I wiped, there was almost mucous like brown discharge. Although my doctor told me this could happen, I'm still nervous. Anyone else have experience with this? Is this normal and okay? Also, no cramps or anything.
