Confused. Need Advice/Thoughts Or Same Experience.

Hi. Nakunan ako Dec. 9, 2019 and nag-bleed ako until Dec 22, 2019. Jan 16 to 21, 2020 - Menstruation (25 days cycle) Feb 10 to 13, 2020 - Menstruation (20 days cycle) Mar 1 to 5, 2020 - Menstruation Average cycle ko po is 25 days. Supposedly March 26 to 30 ulit menstruation ko. Nag-PT ako March 26 pero Negative. April 1 - Negative pa rin. Before pa ako ma-delay sumasakit na balakang ko at side ng boobs ko. Halos everyday until now ganun po. Di ko alam kung PMS o Early Pregnancy Symptoms. Di naman po makalabas due to the current crisis. Ano po say nyo?
