Welcome to HCM,
You have mentioned that, this time your period is different. Bleeding during periods is of bright red colour containing lot of clots in it. Implantation
bleeding is very light (spottings) and pink/brown in colour. Menstrual periods are dependent upon ovulation. If ovulation fails to occur in a particular month due to any reason, period will also not follow. You require investigations, thus please consult a gynaecologist.
Wish you good health & early conception,
