TTC/Wanting to give up

Who would've thought TTC would be so hard? I thought it was just having sex and getting the semen inside of you and BAYM YOUR PREGNANT but apparently it's not. I've been trying to conceive for almost 4 months and I feel like giving up. I just keep getting tried of being disappointed and devastated every time. It's very heartbreaking because I get my hopes up and then suddenly AFlow starts to kick in... I feel like the more I try the more it's not going to happen... 😔
