Heres my story:

My boyfriend and I fooled around July 27th. BUT DID NOT HAVE SEX. I have never had intercourse. We keep our hands on each other but I don't know if he accidently got some precum on his fingers. I didn't think anything of it and I was supposed to start my next period on Aug. 30, but it came 2 days late. Although this had been part of my normal fluctuation in the past, I just got freaked out and i took a pregnancy test the morning before I started my period and it was negative.

Stupidly I continued to look online to see if you could still have a period and be pregnant. So I took another test about a week later, it was still negative. And that relieved my fears.

My second period was supposed to start on Aug. 29th and I had the normal premenstrual symptoms but now I'm a week late. I'm super stressed out about this and I know that stress can delay your period. I took another pregnancy test yesterday that was negative. If I was pregnant I would be like 7-9 weeks pregnant right? And that would definitely give me a positive test?

Please give me any advice!!!!
