Hhheeelllpppp!

Mrs • I`m 33 w/3 daughters & a 1 son.. I have been w/my husband 15 yrs, but only been married 5 yrs
So this morning I posted saying my af was here. But I only seen light pink when I wiped. Now it's nothing! What should I do? Confused! Should I wait the day out? I'm usually light anyways but it's usually constant. I usually cramp too but this time none of that. Any suggestions?
