Getting pregnant while on drugs

I had symptoms before but I didn't want to admit that something was wrong and the symptoms came very early in my pregnancy and everyone (friends) kept telling me I needed to take a test they even bought it and said " its here for when your ready for it" I had it for like 3 days I waited until I was alone and I took it and of course it popped up quickly the first person I told was liz who was my very best friend that was January 15th 2019 that was also the last day I ever did meth (yes I found out I was pregnant while I was high)
