Should I Contact my Doctor?

Tiffany • God is good. ❤️
I feel like I call my doctor for everything. Anyway from last July- this July my cycle has stayed between 28 & 29 days. All of the sudden they jumped to 36 days last cycle & now 38 this cycle. Has this happened to any of you? Should I be worried? What types of things will my doctor be looking for if any? I'm a nervous wreck that we aren't going to get pregnant or that I have something wrong for that matter. 😕😢
