hello... thanks for trusting the healthcare magic doctors for ur health related queries. I guess ur concern is about..should I try for natural conception or IVF after third miscarriage...right. well...my answer is..YES. u can try for natural conception after third miscarriage. as u told that u had conceive for two times naturally. so there is HIGH CHANCES of conception by natural method.u can go through it without any doubt in ur mind. secondly let us discuss about the miscarriage u had. u told that u had miscarriage at 4 n 11week....right. so most of the time it is usually happens if there is any chromosomal or genetic abnormalities having in embryo, or any infections in mother or sometimes it is unexplained. so DON T LOSE HOPE...KEEP PATIENCE. u can get pregnant with natural methods. if u r come under the reproductive age group(women from 15-45 years are came under this group. in this group chances of getting pregnancy is high) and u r having regular menses then chances of getting pregnancy is DOUBLE.bur u didn t give info regarding ur menses n ur age.so it is difficult for me to comment on this. if u have both then RELAX, NOTHING TO WORRY. with the above discussion u can try out my suggestions- 1. there is high chances of getting pregnancy with the natural method. so RELAX, RELAX.. 2. try to do coitus during fertile period(it is from 10th to 16th day of menses) during this period chances of getting pregnancy is high.so do coitus as more as possible during this period. 3. if u r in hurry then visit nearby gynecologist or infertility specialist. he/she can help u. I hope the above information is useful, informative and helpful for u. regards- Dr sudha rani panagar (i can understand ur situation, but DON T WORRY. EVERY PROBLEM HAVE SOLUTION. I pray the God that u will be blessed with a cute n healthy baby..hopefully TWINS)
