Spotting at 28wks!?

B
Ok I HAD placenta previa originally, but it has moved since my 20wk check up. I did not have sex last night or yesterday at all. I just went pee and had bright pink on my tissue. I have a terrible cold which I think is actually strep throat at this point and had been coughing like hell BUT I didn't start coughing until after I made to the bathroom just now. So it's hard to believe I coughed & burst something because it was there already. I googled it (cautiously, I know) and one or two articles said I should go to dr. asap even with no cramping because I'm 28wks. My dr office isn't even open right now and they always tell me to avoid going to the er. He's (baby) moving around and everything. I'm just nervous as hell.
