Trying to conceive

Deedee

So me and my partner have been together 2 years and been trying to conceive for a year but no luck, any advice on what to do and what’s the best thing to do to conceive as my partner has already got a kid but I haven’t, we’ve been trying for a year but no luck I’ve had little pregnancy symptoms but always came back negative any advice or help to conceive is helpful

Thank you
