Is it normal to be pregnant again after 6 months cs (bikini incision ) cause i had complete placental abruption at 31 weeks and i lost my baby ?

C section : You having a C-section and an abruption has really nothing to do with getting pregnant again. Most bottle feeding mom's start ovulating again as early as 2 weeks after delivery. If you had any bad habits like smoking or drug use the last time, stop them asap. Otherwise it may be time for a perinatology consult to evaluate your risks.

Not optimal plan.: A short inter-pregnancy interval is never advisable. You are now at risk for recurrent abruption, repeat cesarean section, preterm labor, uterine rupture, poor fetal growth, anemia and placenta accreta. Seek mfm care asap, take Folic Acid 1-5 mg daily and avoid smoking/cocaine. Best of luck!
