Not sure what's going on?

Brandi-lea • Khaleesi-May Dizney Van Vliet - my precious daughter born on 23.6.15 👶🏼🌸
Ive missed this months period (in 7 days late) But I don't know how to show glow that I haven't come on?
​If I try to delete the period it just throws in another one for the following week. Seriously confused as it also changes all of my ovulation dates, what do I do?
