Can I have some opinions please

So... I had our baby 7 months ago and we really want to try again. We originally said we would actively try in December but of course if it happens before then great. Anyway as we are not actively trying yet I haven't bothered with opks or anything like I usually would. But I noticed I had ewcm on the 10th and 11th October. We had sex twice on the 13th October and when I looked at my app it showed I was actually ovulating around the time we had sex. So then I took a few opks on the 14th and today and they've came back negative. Do you think there's a chance I could of conceived this month? We would be super happy if we did even though we agreed December we would start 'trying' the excitement and anxious feeling is real
