Blood pressure question!!

I am 31 weeks pregnant with my 2nd baby - Does anyone else here get high spiked blood pressures after eating certain foods this late in pregnancy?? I ate these same foods early in pregnancy and it had no effect but today I had a lemonade and a chicken sandwich from chic fil a and my pulse went up to 143 and my blood pressure went above 140 and I called my Ob and they want me to come in and be checked which is scaring me because I have heard stories about high blood pressure in pregnancy and I have never had high Bp. Has anyone made it full term with random high blood pressures at times??

I would really like to hear from mamas who experienced preeclampsia as well?? How did it start? Im very nervous now because baby is not big enough to come.
