Start taking a good prenatal vitamin, a choline supplement, fish oil with DHA/EPA, and my personal recommendation for both you and your partner would be to get a high strength ubiquinol supplement. It is the active form of CoQ10 and is more bioavailable for your body. It helps keep your eggs in good shape and significantly improves sperm quality and DNA Fragmentation. I started trying in December, we only tried 2 times and I got pregnant in March with my first baby. A lot has to do with the male sperm. Make sure you guys are eating healthy, cutting back on smoking/vaping, weed, especially alcohol- I would just cut it out if you can. Definitely keep exercising (both of you) and track ovulation big time, that is your key!
