Pregnancy

I had my daughter on 11/19/17 via C section.. me and my husband had unprotected sex 2 weeks after I had her.. this morning I woke up and after I had urinated I wiped and there was pink.. I have not had my first period after birth yet but know you ovulate earlier than you get it and know there’s a chance it could be the start of my first period. How likely is it that I could be pregnant again or could be period? Please no hate I am very scared considering the risks but have nobody else to talk about this with.. posting anon for obvious reasons. We had sex dec. 3 and it’s now dec 28th

UPDATE!!! i took a test this morning and it was negative!
