TTC BABY ONE!!

Hi Ladies, I'm hoping that even just one of you can help me out. First time I used opk this month and got my positives very strong on the Friday morning at 6am and 6pm that day. I tested again Saturday and have very strong lines again. We bd on both of these days. What are the chances of falling pregnant?? I have had cramping on the Friday and Saturfay and some cramping today on the Tuedday as well. Can anyone please tell me anything is valued! Also when should I take a test? Thank you xx Baby dust to all!!
