Late???

So I’m 3 days late and having the “ period “ symptoms but no period and I’ve been regular since I was 15 ... like clock work ... and yes my hubby and I had sex.. a lot of sex during my high fertile days in February the 16-18 ... sooooo what’s the possibility of me getting or being pregnant??? And when should I or see the Dr?

Would like the input ... please and thank you

And we are ttc
