feeling down

Just having an off day! Tomorrow will mark 3 weeks since I MC and some days are easier then others. Wondering if AF will show Monday or if my body is still off. No sore boobs or anything else like I have right before AF. Someone said your more fertile after you MC but we haven't tried cause we want to wait all though we have been intimate but safe but there is still that chance then yesterday I was talking to my mom and she knows we had a MC and she says "so do I have a new grand baby on the way?" Which I don't think she thought about it but I nicely replied mom it hasn't even been 3 weeks and we want to wait for normal cycle and she comes back to with well maybe it will be my Christmas present. I just said I don't know...ugh and everyone on my fb seems to be pregnant. I don't know anymore I'm just down I guess
