Yes I agreed with Asha. Wait 2 or 3years because of C section. And think about present covid situation. How can you manage with your babies. Your babies are small and to next pregnancy you need help for babies care.
1st delivery c section means next delivery also c section. So that time very typical and hard for you. Compulsory some one have to stay with you. Once think about present and future.
Once consult gynecologist and she will explain about this.

Hi don't do work which put strain on the pelvis and take simple homemade food like khichdi and daliya etc

Wait for 1 more week... sometimes periods can delay upto 1 or 2 weeks bcoz of hormone imbalance.. or bcoz of stress.... Drink plenty of water.... After a week consult with gynec.

Some women don't get any symptoms or could not recognise. Once call to doctor. She is ready to delivery.. Don't wait for suggestions. Consult immediately.

han my ny kaha apny hasband ko wo kehry hn k next week k start py ly jahon ga

Fallow doctor's suggestions. They only examin and clear your doubts.

Hormonal imbalance,,, irregular periods,,, pcod or pcos,,,or may be some other reasons.... but these r the main reasons for infertility.... But without dr's advice u can't say anything.... Dr. Will examine and they can tell u exact reason...and then go according to doctor's advice....

R u taking calcium n multi vit. Supplements ? Since after ur c section... There must be some reason behind this.. may be bcoz of any vit. Deficiency...anemic.... Get it checked by dr. Properly .. if u r breastfeeding then loosing weight this much.... It's quite normal.... I was of same weight before and after... But as baby starts eating solids... U will get back in normal weight....

Periods missing for more than 7 days or more is the main symptom of pregnancy .Later vomiting, morning sickness , feeling weak r next symptoms after almost 1 month of confirmed pregnancy.Body pain in some women in later months of pregnancy.Its better to clear it doubts with Gyneac

What's ur baby's present weight?
