Okay, so the subject title doesn't really reflect how I feel about the situation, (I actually do know what I should be doing), but I thought it would get some of your attention. Anyway I'm 16 years old and this is my second 'Pregnancy Concern' post.
I'm sorry that this is probably going to be very long and detailed, but I've been holding this in for too long and now I just feel like I really need to talk to someone about it...So, here it is: Me and this guy had intercourse on the 18th of October; and no we did not use protection, I know we should so you don't need to tell me (Sorry if that sounded snippy

).
Now, I have an extremely irregular period, (varying from 20-35 day intervals), but I decided to sit down with a calender and try to figure out when my period should arrive. Going on a 30-day cycle my period should have arrived on approx. Oct. 20th (2 days after we had intercourse). On day 41, I started to suspect, so I took a HPT and recieved a negative. But today is day 46 and still no period. Last week I had cramps that felt like my period and I was sure it was going to start, but it never happened.
So now what? When should I take another test? When should I go for a blood test? My cycle is irregular but it has never been this long. I'm sorry to drop this on everybody, but honestly I really don't have anyone I can talk to about this in my life right now.
Thank you for any advice you can offer.
