hello, Pregnancy is only possible if you are sexually active and do unprotected intercourse around ovulation time in regular cycle. Above said clinical features may be due to hormonal imbalance, mental stress, vaginal or pelvic infection, psychological upset or early implantation bleeding etc. I suggest you to undergo one blood test for beta-hCG and pelvic ultrasound scan to rule out the underlying pathology (if any). Kindly, consult with your gynecologist and take advice. Wear tight breast support and take PRIMOSA cap 1000mg daily to relief breast problem. Take healthy diet, avoid stress and sleep properly. Be well.
