Feelings the week of conception

I have a 6 month old and haven't had my period yet, so I don't know when I'll ovulate. I did the deed on Monday hoping to get pregnant again. I kinda feel almost cramps / weird feeling. I don't know if it's ovulation or almost-period. My first pregnancy, I had immediate signs, like that very week of conception. Did you get any feelings the week of conception? I wonder if I conceived. I was lucky before - I got pregnant on the first try.
