Delayed Menstration

No to bash pls. July 16 ng umaga nag d9 kami ni huby with condom naman, on the same day at night nagkaroon ako natapos ako july 21 natapos ang mens ko. July 25 nagdo kami ulit unprotected..pero safeday pa naman yun diba? Aug. 24 nag do ulit kami unproted ulit pero hindi naman siya nag come. My question is bakit hanggang ngayon(sept. 3 na) wala pa rin ako mens.. Ps. Nag PT na po ako at negaTive ang result. Does anyone experience these? #pls respect.
