yes baby lubricant

What's your guys thoughts? I've read a few negative things saying it gives woman yeast infections and other things, but I've heard positive thing about it also, I want to use it cause we struggle making a baby, but at the same time I don't want to use it because if hearing what it causes woman in their vagina. I think I may be allergic to my partners sperm because I've had PID (pelvic inflammatory disease) from having heaps of unprotected sex, but when I take it easy I don't get it, but we've just started trying again and I had a yucky tummy like when I get PID, Again after 3 times unprotected sex, and I don't want to try yes baby lube if it could make it worse, but yet again it could help? What's your thoughts ladies, I need help.
