When did your symptoms start?

It hit me like a truck last night… I am about 4 weeks along and have been dealing with light constipation, and nausea. Last night took the cake… I woke up at midnight in some serious pain the kind you get when you need to use the bathroom but you can’t. That brought in the nausea and it was just a very bad night. I ended up being able to use the restroom and feel back asleep. No bleeding and only slight cramping.
