Ladies so was suppose to ovulate Sunday with my glow app and this morning did an opk clear blue digital advanced and was a flashing smiley. I had planned to see my partner tommorrow evening. Well notice discharge gettin wetter not stringy yet so thought I still have time. But been having pain on my left side and decided to take another right now and I got the solid smiley!!!!!!!!!! This shouldn’t be coming up till tommorrow or Sunday! And I haven’t seen him all week!!!. What do I do and looks like I’ve missed my chance for this cycle and have fertility appointment first one Thursday!!!!!! Advice
