Please Help!

Hey ladies,

Im in desperate need of advice and insight. I began my last period January 26th, 2024. My cycle lasted about 5 days and was on the lighter side with minimal cramping. It ended January 31st, 2024.

That following Saturday (3 days after my period ended, I had a lot of unprotected sex with my boyfriend and he came inside me multiple times).

Then the next morning on Sunday, I took a Plan B. I’ve taken Plan B before and never had any side effects or bleeding caused by it.

However last night I felt really nauseous and light headed after dinner. And today I noticed I have brown discharge but it’s a decent amount and I had to put on a pad.

Today is my predicted ovulation day, but it’s also important to mention that Ive never had ovulation bleeding before either.

This brown discharge/ blood is very abnormal for me compiled with the nausea and occasional light headedness.

What could be the cause of this? Is there a chance I could be pregnant? I don’t know what’s happening or what I should do.

Help!!
