TTC and new supplements

Natasha • I`m 25 years old, I had excision surgery for stage 4 endometriosis in October 2016. Endo already growing back due to trying for baby. Husband has testicular failure. Looking for positivity 💞
Ok so I've read a few things about supplements helping fertility, so I'm going to add two new ones to my list asides the Iron and Pregnacare. I've recently been told Bee Propolis and Flaxseed containing omega 3,6,9 have helped massively. Has anyone ever tried either? TIA
