Hi, Its a pleasure to answer this question for you.
If I were your treating Obstetrician, I would not ignore this symptom as you already have a history of preterm labor
. Also the worry itself is enough to raise your blood pressure so early on in pregnancy
I recommend that you get yourself examined as a weakness in the cervix
[foremost part of the uterus], or infections commonly cause preterm labor. However , both the causes can be easily treated with bed rest
, antibiotics if needed, progesterone
supplement and if the cervix is weak by applying a stitch to tighten it [encerclage].
Also since your BP shoots up, it is wise to get a urine examination done for proteins
as this may be early onset preeclampsia
[a condition specific to pregnancy where Blood Pressure rises and proteins appear in urine] so that it can be treated too.
I would like to congratulate you for being vigilant enough to recognize these problems and seek help early on.
Hope I was able to help. Also please feel free to ask any further questions to me as preterm labor and preeclampsia are my special areas of interest.
Thanks and have a great day.
