I really recommend getting a test panel done with hertility health
We used their fertility lubricant and it was great for us. I don't produce much EWM so I think the lube helped the swimmers on their way brilliantly. It's not cheap but we found that the recommended amount was waaaay too much and actually used syringes to measure out just 1.5ml each time. Sounds very clinical, but it wasn't as moodkilling as we expected. Whether we just got lucky with our conceptions or not, we'd absolutely use it again to eliminate that one obstacle.
I’m trying them now hoping they work I have the partner one though think it always helps if you are both taking something
