Help pls!

So my period is irregular but in January i had my period the 7th-14th and in February, i got my period the 4th-11th. In the beginning of March, I had pink/red spotting for 4days straight. After that i haven’t had my period. Since February was short, i expected my period to come March 7th or around that week but nothing. Ive had protected sex all throughout February. I always have sex with a condom and my bf does not cum inside of me, he always pulls out. Can anyone give me advice on what should i do? I’m freaking out.
