I have been TTC for four months Jan 2014 I have two fraternal angel baby's who was born at the 22week mark!
Me and my DH are TTC last month my chart was all over the place and I am pretty sure it was a anovulatory cycle. I will show the chart.
April 2 to May 4th 2014.

I kept having pos opks my body kept gearing up to o and never did but this month I had a way better cycle. This is my chart for
May 5th to May 28th

In between this cycle I only spotted for three days I usually full fledge af for 5 days so I don't know what that was about but that has never happened. So as you can see I did O today I am 6DPO and these were both my opk test images.

Does anyone know what this could mean??
I am a little confused and I don't usually get confused easy last month was a crazy confusion not only was my chart off the wall but I was getting very faint positive hpt- It ended up to be all negin the end though I don't know.
Could this be a early sign of pregnancy?

Any one else get very strong positive opks before a positive pregnancy test?

I don't have any experience with that but have heard you can get a positive opk before af arrives also. Hope it turns out to be a BFP.
