8 days with positive opk. All definately darker than control line. Today was my first negative. Im 5dpo today. Confirmed by temp drop and spike. Wondering why all the positives? Cycles have been normal 28-32 day cycles. Had a chemical pregnancy last month now on cycle day 30 (expected this since i still had hcg for a few days into this cycle). I have heard possibly more fertile after miscarriage (i know im already pretty fertile cause o already have 7 kids) could this be a sign of double oculation? Any reason the surge could have lasted so long?
