Am I Pregnant??

Helen

Last Month 'July' I missed my period but during the time I was supposed to have my period I was feeling tingling all through my chest to my stomach like butterflies. I was also getting mild, constipated, bloating and had a lot of gas. I have two test both negative one at home one and doctors and now 'monday' I got my period but it lighter than usual so I'm having second thoughts I'm not sure what to think?
