I need some encouragement

I've been dating this guy for three months, and it got serious really fast. Right before I met him, my body healed itself from the symptoms of PCOS and for the first time in my life I've had a normal period for 6 months straight. Now, I'm officially a week late and I'm too scared to get a pregnancy test it make a doctor's appointment. On one hand, I know I'm not pregnant because I just can't be. On the other hand, what if I am pregnant? I haven't talked to my bf about it because he's been sketchy the last couple of weeks and I don't think he's as ready for a serious relationship as he might think, let alone a baby. I haven't seen him in over 2 weeks and haven't talked to him at all in the last few days.

I'm really unsure what to do. I just feel so alone.
