2 years ago I had a preterm labor at 20 weeks. Now I'm pregnant again with a girl and I'm 25 weeks, my doctor reassures me that I have a healthy pregnancy and that everything is fine. But i find myself being hesitate to buy anything because am scared that something will go wrong. Positivity is everything, getting over the fear is hard to.
