Positive test, NEED ADVICE!

Kc🧜🏼‍♀️ • mj7/23/19🦋🦄

Ok so my period was a few days late but I didn’t think anything of it because my period is sometimes irregular AND my stomach has been cramping off and on the past 2 weeks. Well today I realized I’m a week late. Took a test and it’s positive!!! My husband and I are extremely happy and excited. This is our first! BUT the problem is Friday night friends came over and I drank.. a lot. Now I’m worried I might lose it. I need advice
