Hallow Dear, Trust pills are birth control pills having Ethanol estradiol, levonorgestrel and ferrous fumarate. The last is iron to complete 28 days. First two are the hormonal components which give the effect of birth control. After getting the menses, you shifted to Daphne which contains Lynestrenol (Progesterone). Both these pills are good birth control pills provided they are consumed regularly. However, I would suggest you to stick to Trust. You had sexual intercourse 3 days after your menstruation while on the pills. So the chances of the pregnancy are very rare. When you are taking birth control pills regularly, you are well protected from the pregnancy, whenever you may have intercourse. Moreover, your intercourse was not during the fertile period. !4 days prior to the next menses (when you are not on pills), the egg release (ovulation) occurs. Egg has got a life of 24 hours and sperms are active for 72 hours. Hence, a period of about one week around the day of ovulation is considered as fertile period. Your intercourse was far away from this period. Also, you are not having any feel of the pregnancy too. Furthermore, you are on the pills regularly. So you are not forming eggs. Therefore, most probably you are not pregnant. The delay in your menstruation may be due to change and irregularity in the composition of the pills. Progesterone only pills are known to cause less bleeding. Delay by two days should not be considered as delay. Still to confirm the diagnosis, please wait for 1 week more and then perform urine pregnancy test on the overnight morning first urine sample. Earlier these tests may give false negative results. If you do not want to wait that long, you may go for Beta Chat Doctor test which gives reliable results even few days before missing period. This should take away your stress. And finally, even if the pills have failed (which is very rare) and you are pregnant, you can terminate the pregnancy safely by medicines up to 9 weeks. I hope this helps you.
