If you felt moving or kicking you would have to be at least about 4+ months along. At that point you wouldn't be getting faint positives.
it could just be normal twinges inside your body. you should probably make an appointment to go see your OB doctor and see what really is going on, and if he/she can help you get more regular periods if indeed you are ttc. best of luck to you! have you taken a digital test?
i am 15 weeks and for the last week or so i have felt the baby moving kicking and having a good old play around although the kicks arent strong enough for other people to feel yet. I would book an appointment with your Dr and have a pregnancy blood test done to confirm if you are or not other symptoms to be looking are sore breasts, nausea vomitting bloating increased appetite. Good Luck and i hope the result turns out the way you want.
