so confused... could I be pregnant?

Le

so my period is currently a week late. my hubby and I have had sex twice in the past 4 days. every time after sex I get light pink spotting and then it is gone after 1 wipe. could this be because I am pregnant? I keep feelibg like AF will show Any day, but so far nothing. has anyone else ever experienced this and ended up being pregnant? I took a test today and got a negative. I am going for a blood test tomorrow to confirm.
