Help- recovering addict

I found out I’m pregnant feb 20. I’m now 15w6d. The day I found out I quit, cold turkey all together. I feel like I’ve been clean for forever. But now, idk why but especially today, I’ve been having urges to use. Really bad urges. Anyone have any words of encouragement or advice on what to do. Please.

My drug of choice was meth.

I haven’t used at all since I found out and I’m getting so overwhelmed trying to fight the want to smoke. This is so hard.
