Questions!!

So I'm 2 days past due for my period.. I was switching between nexplanon and the pill and had only been on the pill for 2 days.. Had a party at my house and about 10 cups of mixed drinks and 5 shots of tequila later me and my boyfriend had sex and the pull out thing didn't quite work lol .. I enjoy been sick (back pain, nausea, headaches) for the past couple days.. Took two pregnancy test but I think it might be to early for that but even so with my daughter I was two months pregnant and still failing hpt and they had to draw blood and do an ultrasound.. Should I wait and go to the doctors to get my blood drawn? Wait for my period? How long should I wait?
