Heart broken

So a few days ago I got a positive on a pregnancy test. I've tested 2 more times since then and I have received negatives. It was devastating for me to get that positive followed by negatives. All I've ever wanted these past few months is to have a baby. My period is irregular in a sense that I skip a month but know I'll get it the following month. I'm on the second month with no sign of af. My breast were tender and I was extremely exhausted which prompted me to test in the first place. I'm just so frustrated... Everyone around me is having kids "by accident" and we've been trying and haven't conceived. #hopingforababysoon #babydustplease
