Morning After Pill

I have a very complicated morning after pill situation... I ended my period on 4-16 and had unprotected sex. The next day I took a morning after pill. Then on 4-23 I had unprotected sex again and took the morning after pill the very next day. Then on 4-25 I had protected sex but the condom came off during so I took yet another morning after pill a few hours later. I believe I was in my ovulation window during 4-20 through the 28th (give or take) so I’m scared the morning after pills I took may not work. I’ve had some slight cramping and some lower back pain but nothing too bad. I’ve also had more discharge than normal. My question is is all of this happening because the morning after pill is working or is it happening because it isn’t working? I’m extremely scared and have done my fair share of googling and it only scares me more. I’d love some thoughts and some peace of mind.
