HELP! Can I Be PREGNANT? 😣 help me ease my mind!

Ok so I just had a baby about 4 months ago. First time mom. And I’ve been so scared to be sexually active again due to the simple fact I am not ready to be pregnant again. I had sex on the 27th of September no condoms but we did pull out method (first time doing anything since pp) but I Psyched myself out and ran to the store for ovulation test and plan b. My period app states I was ovulating but not at peak. And the clear blue ovulation test said I was not ovulating at all. Fast forward to today. I am having cramping, very very light spotting and my period is set to be begin in 5 days. Can I be pregnant? Please help ease my mind! Also the reason why I’ve been traumatized to even have sex was because with my first pregnancy plan b failed and birth control. And I am married for anyone wondering.

EDIT* reason why I haven’t taken a pregnancy test either is because it would still be too early
