Hi Dhanya,
Welcome to Health Care Magic,
I think, your Doctor might have said that there are more chances of C-sec, because of short interval delivery. Did you have any complications during your last
pregnancy, delivery or after delivery? Were you Anaemic ( less
haemoglobin), any
heart disease,
high blood pressure, or any medical problem? Did you bled too much after delivery? Was there any extensive perineal or cervical tear, or infection in the episiotomy? Was there any problem in delivery of Placenta?
In absence of any of the above factor, In my opinion, the birth interval is just fine. At your age , I do think that this is the right time to have another pregnancy.
You may just ask the Doctor if there is any reason, she said so?
Relax and Enjoy pregnancy. If at all even you have to have C-Section, because of some genuine reason, it is okay. You should not worry from now. Just make sure that you are taking Iron and
calcium supplements and do good exercise specific for pregnancy. ususally second delivery would be much easier than the first one.
Good Luck.
