diagnosed with placenta previa

So this is baby number 4 and pregnancy number 6 for me, I went in for some spotting and after an ultrasound I was told I have placenta previa. I'm 18weeks just wondering if anyone else has delt with this and if it corrected its self or any issues you had because of it. As of right now I was told no strenuous activity, no lifting and no intercourse. I am a GM at my job and it's very face paced so it's hard to take it easy and as for the no intercourse well that's just a bummer but I will manage if it's for baby!
