I got home pregnancy kits which were all negative, and a beta hcg test which measured 0.43 but I'm feeling fluttering in my stomach. I've got my periods 2 months prior  because of the taking regestrone cr 10 and prior to the test and have had no intercourse. it's been 22 weeks since last intercourse but I'm feeling something in my stomach but it's not like a bump. is there any chance of pregnancy or it could be due to another reason?
