5 weeks 1 day...spotting?!

Stephanie
Hi, I'm pregnant with my first and am 5w 1d and having a little bit of red and then pink spotting. Is this normal? Should I be worried? Trying not to freak out but of course I'm scared! Having some cramping but I'm pretty sure it's due to gas. Also, my husband and I had sex this morning for the first time since finding out..Help me!!
