Before answering your query, I would like to ask some questions-
1. Have you confirmed your pregnancy using pregnancy test kit because you have mentioned that you felt like you are pregnant? It is very handy and easy to use even at home. Please use that and first get confirmed about pregnancy.
2. If your periods are delayed and you are suspecting your pregnancy, then there are strong chances that the tablet you had for delayed period has worked well for you and there is nothing related to pregnancy.
3. If your pregnancy is confirmed, consult a doctor/ gynecologist and share that you have taken that tablet. As per my knowledge, it would not be a problem because if you are pregnant, there is no egg to be acted upon for the tablet to delay your periods.
Secondly, if you were intended to delay your menstrual period means your pregnancy is recent and there should be minimal harm.
Lastly, you want to wait, you can wait for few more days. If you will have your delayed periods then there is no pregnancy. But this is doubtful because in many cases, females faces problem of menstruation cycle even after conceiving during their initial days. So, the best solution is to use pregnancy test kit available at any medical store. You just have to collect a part of your first urine in the morning and apply a single drop of it in the ELISA strip using dropper provided with the kit. Within a minute, you will be having result in your hand.
