Pregnant or Not

Hello mga Momsh. Pa help naman po please. I gave birth 3 months ago (October) and around 2 months after giving birth nag DO kami ni hubby once and we did it using pull out method po. I had my period last Dec 15, 2021 and now hindi pa rin dumadating period ko for month of January. Before I got pregnant irreg na talaga period ko so I don't know if I am pregnant or not. I haven't done a PT pa kasi natatakot ako. Please advice naman. 🥺 #advicepls #pleasehelp #pregnancy
