Slightly upset

Downloaded this app yesterday as it sounds amazing and is but all other apps said id ovulate last weekend and this one said that yesterday was my highest chance to fall pregnant so when. It came to doing te deed it was great but hubby couldn't follow through ( we've bd for the 12 days) I'm now sitting here rather upset that I've probably wasted a shot of my clomid for nothing :( any words of support or advice?
