Plan b late period

So I’m writing this just in case someone else is going through what I went through. So I had sex with my significant other in January (unprotected) and things got carried away and yes he came in me 🤦🏾‍♀️ I took plan b probably 3 hours later. But I did not I was ovulating at the time smh... so I got scared and started to worry. 5 days later I started to bleed feeling relieved but confused because I just finished my period a week before the unprotected sex and it wayyy to early for my period to come like 3 weeks early! So basically I had to 2 periods in one month. I googled all the side effects of plan b and came across breakthrough bleeding. So again I got scared because I still could be pregnant. So I waited to see if my period would come this month February. I had severe nausea and I just knew I was pregnant 😩 few days later I got period 🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾 thank goodness because I just had my third daughter 3 months ago and not ready for another child!! But plan b messed me up so bad! With nausea cramps moodiness every thing! I’m planning on getting on BC ASAP because I’m not going through this again.
