Feeling discouraged? :(

I'm 7dpo today and have been having AF like cramping almost all day. I had a bit of cramps yesterday too. But I read somewhere that implantation cramps will only last 5 minutes and then go away.

With our daughter I remember feeling like like AF was coming but i didn't really note the difference between that and implantation cramps.

I also had cramps at 8dpo last cycle and thought for sure they were implantation cramps and I ended up not being pregnant, and I was so shocked because I thought for sure i had felt them.

We're using a donor and at home insem so I'm worried I didn't get the donation up high enough. :(

Just wanted to rant, because I'm super convinced we are out this month. So tired of seeing BFNs though...
