I have a question ??

Misty • I have 5 boys. I’m over 40 and my S/O is 17 years younger than me. We are trying for his and our first child. We can`t wait to see what our DNA creates!!!

Can you still ovulate and the OPK strip not pick up on it because I know for a fact that I ovulated last night while we were at the movies. But I didn’t have a Positive OPK. I know what it feels like to ovulate. I haven’t ovulated since September. Just asking.
