Buntis ba or hindi?? I stopped my pills last Aug '20. Today my 9th day missed period from EMP121420

(I am a mother of 2. 16 & 9 yrs old) 9 days nako delayed Negative result ng PT. Pero sobrang masakit puson at balakang ko almost 5 days na.. Ibang iba sa 2 kids ko ung exp ko ngaun. Kaya medyo magulo sakin kung buntis ba ako or hindi. Last period ko was dec 14 '20, i am 28-30 days cycle pero di ako nagka mens nung jan 14. Tingin ko naman di ako stress at wala nman akong iniinom na gamot lately. Very normal ang katawan at mens ko even with pills and w/o pills.. Napapa iling nalang ako sa sakit ng buong tyan ko. Anyone here with de same experience.. Para kong virgin this time.. Missed period at cramps ang naeexperience ko right now. And even in my 2 kids walang signs and symptoms. Di ako maselan magbuntis or walang arte sa katawan.. #advicepls #suggestionpls #anyExperiencelikethis?
