Preseed, to try or not to try?

Question for preseed users, if anyone who would be so kind as to reply...
Did you use preseed instead of other lubricants you were using before or just as an addition to your TTC procedures? The SO and I don't usually use lube, we don't feel we need it, but I'm wondering if we should try preseed anyways...
Dunno if it would help but we have been TTC for about 8 months. I was super sick in my last two ovulation cycles so we missed those windows. I'm really bummed about missing the last two cycles and in general am getting so impatient trying to wait for this to happen. I'm 30 and I feel like the clock is ticking soooo loudly. If it doesn't happen soon I think we might just give up altogether. 😔
