Positive result this morning but was out drinking last night eek!

We've been trying for a baby for over half a year (I know not long compared to some but it felt like a lifetime!). I have been so good not drinking until my period arrived each month but this month I didn't I went to a party last night and drank quite a lot. My boobs were killing me this morning even though it's 5 days to go till my period so curiosity got the better of me took a test and it's positive! I'm so happy but now so scared that due to how much I drank last night and that it's such early days because I took the test so early that it might end in a chemical. I'm so torn between being excited and regretting taking the test so early because if it did end in a chemical I'd be none the wiser.
