Good day doc...well I had my peiod on the 15 th of feb, I know it might be ealry but I had pregnancy symthoms all over again, I did a test on monday and it was positive and one yesterday morning, came out negative and then again one this morning, also negative, could it be that I'm pregnant? I have nusea, painfulle breast, lower back pains, something that feels like period pains, must go to the loo a lot to pee, al the same symthoms with my first born! Advise please
