15 weeks pregnant and blood and mucus in stool

This is gross and I’m sorry. It really only started this week. I’m 15 weeks and 5 days right now. I really started getting worried this morning when I had just blood and mucus come out. I did eat spicy and greasy food last night (stupid cravings). But I didn’t think that could cause something like this. Now my doctor wants me to come in to get a stool sample and I’m trying not to stress out. Im 27 and don’t have any family history of any kind of cancer that I’m aware of. I don’t know what I should expect. But I have an almost two year old at home and this new baby on the way, and what if I’m not here to watch them grow up 😭 photo pictured below is gross and I’m sorry. But has anyone else ever experience something like this and it not be cancer?
