hello...
thanks for trusting the healthcare magic doctors for ur health related queries.
I guess ur concern is about..chances of having
pregnancy after using withdrawal method..right.
well...in ur case chances of getting pregnancy is very rare. as u told that both u taking care regarding that. so ..RELAX. there is no chance if ur husband withdraw all his ejaculate outside the vagina.
second thing about ur delay in mens.as u told that u have regular menses but this time it is delayed. it can happen sometime..so DON'T WORRY..RELAX. menses will came.
lastly..u told that u r feeling burpy n gassy. it is sometimes happen, nothing to worry.
with the above discussion u can try out my suggestions-
1. RELAX..KEEP PATIENCE, menses will came, wait for this month. if menses came then nothing to worry. if not then again do pregnancy test.
2. if pregnancy test is negative then visit to nearby gynecologist. he /she can help u.
3. if it is positive then also ur gynecologist will help u.so NOTHING TO WORRY, RELAX.
I hope the above information is useful, informative and helpful for u.
