Doesn't Seem Real...

I just found out I was pregnant yesterday. At least I'm almost positive. Took a test yday with FMU and it was so light I thought I was seeing things and my husband didn't agree. This morning did another FMU and again, so light but this time the husband "sorta" saw it. Had someone tweak it and they said yup! I'm going to test again this weekend to confirm but AF was due today and no regular signs she's coming. I have a little girl but she's 7 so it's been awhile since I did all this. We've been trying for 5 months and are really excited but I can't seem to wrap my head around it being real. I've taken SO MANY tests over the past months and been disappointed that I sorta feel like this is just going to be another months I'm crazy but I've never gotten one that looked ANYTHING like the other two. I have been incredibly short of breath. And my hubby noticed my boobs were bigger and heavier. Has anyone else ever struggled to feel like this is it and no you're not just crazy???
