Pregernant?

So let me start off by saying i was diagnosed with PCOS literally a year ago. Well I’ve not had a period since august. I’ve been having really small pregnancy symptoms but i had two negative tests In October. Well i heard that if you don’t know you’re pregnant and you drink you won’t get drunk. Well that’s been happening. I plan on going to get blood work done. But i really hope i didn’t mess anything up if i am pregnant. Just wanted to vent. If anyone has any advice I’d love to hear it.
