Lubricants & preg
I don't know what is in the lubricant you are taking but my recommendation would be to use a vaginal one instead.
On average it takes 3-6 months for most couples to conceive and majority within 12 months. If you haven't conceived & it's been more than 12 months, see a GYN to discuss your concerns & review medications/ products you are using. If her cycles are irregular, then go sooner to the dr.
