Pregnant or Not

I do not know if im pregnant since im having irregular menstrual cycle. My bf and I did it and two days after my period came. Dec 5, I had my pt and had negative result. From my last period and to this day, I am delayed for 1 month and 17 days. Buntis na ba ako??? I experienced a lot of food cravings, im too emotional, there were days my breast hurts and would sometimes felt my tummy aches. I have been experiencing dizziness for some days and felt week. Haay ano na kaya ito?! #pregnancy #advicepls #1stimemom #momcommunity #UsapangKababaihan
