Trying for a baby!

Hi everyone, I’m wondering if anyone can help me at all or give me advice, I came off contraception in July when my implant had ran out, me and my boyfriend and made the decision to start trying for a baby! We were so excited and was at it like rabbits. 6 month down the line I feel like it’s becoming a bit of a chore to him now, he hasn’t mentioned anything about having a baby for about a month and every time I mention it he kinda shuts it down. I like to make sure I have sex when I’m ovulating too but whenever I tell him that it’s my week or day that I have a higher chance at falling pregnant we almost never have sex! I know we have only been trying 6 months but I feel like he’s gone off the idea but I long for a child! I am so ready to have a baby, I have so many fears I’m scared I won’t be able to have kids or he won’t be able to. Just wanting some advise ladies. Thank you!
