Nifedipine headache ? Preterm labor

Hi, please can you share your experience with it?

I'm only on day 2 of taking nifedipine and I don't think I am gonna continue tomorrow. All day I have had severe headaches and my contractions are still on and off ..

I feel horrible, wondering if I should go to the hospital.

I want my baby to keep baking at least another 3 weeks but not with this medicine. I'm 34 weeks as off today, was 70% effaced 0.5 cm dilated 3 days ago with her head down low and having contractions.

Even with the médecin the contractions haven't stopped.

I'm kinda scared of any progress since I feel them more often after the doc pointed at it.

How did you stop taking that médecin?

Do you think I can still go for 3 weeks with just bed rest ?

Thanks
