I am super nervous. I think I might be pregnant again. After having a preemie with a decently long NICU stay within the past year, I am terrified. My baby is still needing therapy and lots of extra attention. I am also worried about my next baby being premature also. It was preterm labor, which runs in my family, so it's almost a guarantee. I just don't know what to do. I would be about 6 weeks along. Should I buy a test or just wait a couple of weeks to make sure I don't get my period?
