Ok so I am on month 3 ttc after iud removal. I am a poas addict (wondfo and cb advanced) so of course I begin testing early. I know it's typical to have a surge before and during af. I started testing yesterday (my last day of af, no spotting just brown when checking cp) and definite positive with smu then negative in afternoon (both ic), so I though ok after af hormones (didn't test the 2 days before). My cb advanced came in and took with fmu and open circle, here's where is gets weird... smu very positive on ic (took 2 dips in same urine to be sure), ok early ov... so this afternoon I decided to take the cb again with another ic, open circle and definitely negative on ic. All smu and afternoons are on a 4+ hour hold, I don't have pcos, my cycles are regular (same schedule when I had Mirena), I am drinking the same things in the same amount (1 bottle of coke throughout the time plus half a bottle of cranberry at breakfast and lunch right after poas), almost identical everything from yesterday except times poas differed by 30 min. WHAT ON THE HECK?!?!?!? I am so confused and frustrated right now, any insight is GREATLY appreciated! I am going to keep testing.
