Am I pregnant??

on Wednesday 18th I had unprotected sex (day after my period ended) and my boyfriend did the deed in me twice. The day after I woke up with slight cramping and light spotting which lasted for 2 days. I’ve been feeling really tired the past couple of days (more tired than I’ve ever been) I know my body well and I know that this is not normal for my body. we are trying to conceive and the waiting game is the hardest part!! Give me your opinions Please!!
