Hey! First cycle using metformin 1500mg, 3 years ttc number 2. Started opks 4 days ago and this is second urine of the day this morning. Would you class this as positive? It took about 20 minutes to come to this result? Although it was 95% there in the 10 min frame. I took one 3 hours after this and it was a negative result so does that mean I would have just missed my LH surge? Thank you!!
