I know you guys have said countless times but I need advice

I know I’ve had three periods and had two negative pregnancy tests, but after my doctor pushed on my stomach yesterday my stomach has been hurting since yesterday? I became very calm after telling my doctor what was going on and she said you had two negative pregnancy tests so you should be fine. Why does my stomach hurt all of a sudden? I went number 2 this morning and there was a little blood when I wiped?!
