Fell! No more! Need encouraging

Sabrina
So I fell outside today and really hurt my knees. I am in my fertile week right now and was hoping for baby #2. My fiancé and I bd the first day of my cycle and then on the peak day of my fertile cycle. I am hoping that will be good enough to conceive. I have two days left and we won't be able to bd because today he is sick and tomorrow I'll be hurting and we only bd with me on top because he has had a bad back ever since he got back from his last and final deployment. Please anyone give me hope that I can have my rainbow baby this cycle.
