do you think?

I think I could be pregnate but I’m not sure, it’s really weird. My boobs are extremly sore and my nipples are sooo sensitive plus the veins in my breasts seem more visable. I’m about a week late for my period but the other day there was a little bit of blood on the toilet paper after I went to the bathroom but nothing like my period, I don’t really throw up but sometimes like out of nowhere I’ll feel just sick to my stomach. I used to love scrambled eggs but now the smell makes me gag. I have to pee all the time, one day I counted and it was 12 times compared to like my normal 2 or 3. I’m constintaly tired and sleepy, I feel dizzy from time to time, I am so moody it’s not even funny. I also get heartburn and indegestion a lot lately. But here’s the weird part, my future sister-in-law (who is pregnate) had me take a test with her, and it came up negative so she had me wait another week and that one was negative too, she thinks that I am but it’s just not showing up on the test because that’s what happened with her friend both of the times she was pregnate. But since my car broke down I can’t just drive myself to a clinc to get tested and unless I think there’s a good chance I am I don’t want to bring it up to my parents because they hate my fiance and think that we are stupid enough getting married let alone have a kid and my fiance is out of town for work for another to weeks and I REALLY don’t want to wait that long. So if it sounds like I am to you please let me know, I’d really like your help!
