Heya Joey,
Dont worry I know EXACTLY how you feel when you think your having pregnancy symptoms but your AF is just playing games, it feels like nothing can be more cruel.
Im not too familiar with AP (Sorry Im kinda new at this) but you just need to stay strong.
I know its hard, its the hardest thing in the world when you've been waiting and waiting and doing everything right and it seems the waiting game never ends but there is ALWAYS light at the end of the tunnel.

I cant start to imagine how it feels to have been waiting for 3 years 7months and to have had 4 losses is just tragic and I'm so sorry you've had to experience that but I believe your time will come, I know its the last thing you want to hear as Im sure you get told that all the time.

Just know you've always got a shoulder to lean on and open ears and hearts on this forum with women who will always hold you up and try and keep you going when you feel like you cant do it alone.
Dont forget that
