Pregnancy verification. This situation?

I would like to ask if my delayed menstrual period is due to pregnancy or stress? The first day of my last period was February 19,2020. I experienced an increased cravings to food especially those sweets. I also observed that I feel sleepy most of the time, headache became a normal thing. There are times that i am emotionally down (i feel like i am very sad for no particular reason). I also experienced some lower back pains. The pimples in my face were lessen, though I didn't change my skin care routine. This happened to me before but it's a false alarm. I bought two pregnancy tests yesterday and have myself tested. The result's positive. But i can't still be sure of it. I wanted to see a doctor for check up but due to pandemic, i can't just go to a hospital right away. What can i do to have a clearer answer for this situation? I hope you can help me.
