Needing advice

Carrie

So I’m recently married and have been trying to have a baby. Well my period hasn’t come I’m 5 days late and I feel pain in my stomach not the pain that hurts really but its uncomfortable. To top it off I feel bubbles and I’m cramping off and on. My appetite is kinda gone and I’m extremely tired. I thought I was pregnant but it’s reading negative and it’s got me worried. I’ve already been to the dr when this happened the first time last month ( my regular period didn’t come so I tracked how long till and my late period was a week Late ) but my dr said my ovaries were normal and couldn’t see anything. People have been telling me I could be pregnant this time that it’s just not reading but my whole issue is what if I’m not pregnant. Couldn’t these issues make it harder for me to have a baby ?
