I had my last period march15th. We had sex on mar30th and he came inside of me. My next period isn't due until April 16th. I experienced cramping aorund a week ago that subsided 3-4 days ago. My boobs are sore for a while now. I'm emotional and woke up with a head ache today. I also was constipated and gassy and feel very bloated.I feel nausea on and off but not throwing up. Could this be early pregnancy symptoms or just in my head. No need for negative answers (using protection) please as we are trying to get pregnant. Thank you

Early pregnancy symptoms are similar to PMS.
The only way to tell if you are is to take a test AFTER your expected date.

This website sucks!

I'm sorry if thei wasn't what you where expecting, but that's how it goes I'm afraid.
The more you stress about the process the less likely it is to happen. Stress is a majorly bad factor when it comes to conceiving.
Better to relax and enjoy yourselves.
