Pregnancy scare!

Okay so me and my boyfriend have been having sex for months now. Within the last month, we’ve only have sex two times, once protected and once without. When we didn’t use the condom he pulled out waaay before even being close to finishing. Usually when I️m more sexually active that other times my period just happens to be late that month. But, I was supposed to get mine on the 28th of March, now it’s the 6th of April. I spotted a little on the 29th, but that was it, no period. Somebody PLEASEE

Help!
