I am 1 month delayed after I used pills, but I tried to use 4 pregnancy tedt but it all negative, do you think I am just delayed because of the pills?

Have you gained weight? It might be brought about hormonal imbalance. Might as well visit an ob gyne to check your status. It happened to me once, and it is due to hormonal imbalance since I became overweight. My OB prescripted a drug to normalize my menstruation and advised me to lose weight.
