Bed rest at 33 weeks

Hi lovely mamas and mamas-to-be

Yesterday we got a tour of the maternity ward and the postnatal ward! I felt fully prepared... until the midwife noticed that I was having a really hard time compared to all the other pregnant women there..

You see, I have a standing job in retail and over the weekend I really overdid it. On Sunday evening I took a relaxing bath, but afterwards I couldn't get out of it. Luckily my partner helped me and I tried to take it easy for the last 2 days..

The midwife asked what I was feeling and immediately sent me back to the maternity ward to be monitored on the monitor. What turned out: I had already had 5 hours of regular contractions or hardening of the belly. The gynecologist did an internal exam and saw that, luckily, I didn't have any dilation yet (since it was already the second or third time that week I had such a period), but that the baby was already pushing well with its head down.

Honestly, I didn't think it was that serious until the gynecologist gave me 2 weeks of bed rest, medication to definitely delay labor and slow down the contractions, and also prescribed magnesium for the cramps. She immediately talked about an injection to help the lungs mature faster if it didn't improve after a week, and that after two weeks, if it didn't improve, I had to go back, but then to be admitted...

Of course, I barely slept last night due to the tension in my belly, but also because of the worry.

Are there any mamas or mamas-to-be who have experienced this? Should I take steps already in case it turns out to be a premature birth? I feel a bit guilty because I feel like I haven't taken good care of my baby in the last few weeks by always wanting to keep working...
Will it be a premature birth? Anyone have tips for me to stay calm?
