Irregular Period and TTC

I’ve had previous problems with an irregular period, as in I bled for almost 2 years with no breaks. I’ve been to many doctors and there was no explanation to why it was happening. I was on depo and the implant and they did nothing. Now I’m on the patch and it has finally regulated my period. But now me and my boyfriend are wanting to start our family. The only thing I’m scared about is if I take off my patch my period will start again and won’t stop. How can I get pregnant if I’m constantly on my period? Should I just take off my patch and play it by ear?
