Super embarrassed but I need help.

I’m in my 20s and have been extremely reckless lately. So please be nice because I’ve beat myself up a lot the last week..

A month ago I had unprotected sex and I took plan b. My period came a week early but since I’ve had a pregnancy before it wasn’t so bad symptom wise. Fast forward to last week I had unprotected sex again at least four times over 2 days using the pull out method and not using the bathroom in between. Also was my ovulation days and I woke up one morning after using the restroom and I had a pink streak which may have been from ovulating.

Today I am 8dpo and have every symptom in the book. And had some light brown spotting that stopped after an hour. I think I might be pregnant but the test I took was negative and it’s still early on.

I’ve lost a baby before and I’m still going through a lot of hard things in my life that’s why I’m so reckless so ya. Please be nice if possible.

Can anyone tell me what they think?
