Dealing with family pressure to have a baby

Hello All, I’m in need of some advice. Within the last few months my husband and I have been getting pressured from both sides of our family to have a baby and it’s really starting to get on my nerves. What our family doesn’t know, is that we are trying to get pregnant! In fact, we have been trying for 10 months now and it just hasn’t happened yet. The problem I’m having, is this whole process has been very stressful on me and I’m getting concerned that we may need to see a doctor soon because it’s taking so long. We were already told to go in after 6 months of trying, but we wanted to give it a little longer. I’m just getting so tired of the constant comments to “hurry up already”. They have no idea how much this hurts me when they say these things. I want to say something to get them to back off, by at the same time I don’t want to ruin the surprise either. I just don’t know what to do anymore and I’m tired of getting that gut wrenching feeling every time they bring it up to me. Any advice would be appreciated!
