Feeling blue :TTC

My husband and I have been trying for baby #2 for a little more than half a year. So far no luck. False alarms here and there. As of now I haven’t gotten my period in 2 months but I’ve taken like 10 pregnancy tests and they’re all negative. So I’m impatient because I want my period to come so we can try again...... well today my cousin came to visit. She’s the only family that I talk to and visits me. Well she surprised me. She’s 10 weeks pregnant. She hasn’t told anyone. Her boyfriend and her got pregnant the first time they did it without a condom. I’m excited for her, and so happy. Babies are such a blessing. But I’m blue, because she got pregnant so easily, and here I am trying to not stress or think about it, and it’s been more than 6 months. Could something be wrong with me??.... it sure feels like I’ll never be able to get pregnant again...
