I wouldn't worry, pregnancy symptoms can come and go and I think that the body is changing and stretching that much that cramping etc can be a good healthy sign. By all means, if you really are worrying then get it checked for peace of mind, arrange an u/s.
I have a few worries and have arranged an u/s for tomorrow morning.
I wish you well.
I'm sure everything is fine. I have heard with ectopic you have horroble pain in your side and will bleed. If you don't have any symptoms then your like me. I have felt great and I am 9wks as well. Just a little tired and could sleep most the day away if I tried.
go to the doctor! you are 9 weeks, and can be seen--even have an ultrasound to verify that things are OK. make sure you're taking prenatal vitamins as well. best of luck to you...i hope that you and baby are OK!
