Pregnancy symptoms, but negative tests

Hi guys I’m new here. So I was on birth control for three month. April-July (I believe) of this year. In July I was supposed to start my period, with the pills but never did. Im afraid something’s wrong, but I’m not sure. I’ve been having pregnancy symptoms since the 14th and I’ve taken two tests since them and they were both negative. The last test I took was two days ago. Should I keep testing more? I really don’t know what to do. I haven’t had my period since like April or May. Whenever I started the B/C. Im not sure what to do. Thank you all for reading this (if anyone does lol).
