Trying for 2nd baby

Isit normal for mamas that trying for 2nd baby it will take longer times to conceive? Ok im one of them. From i seen having a 2nd baby is faster.. yes using ovulation stick two dark lines. Ihave been trying for baby no2 since April 23. Sperm can live for at least 3 days.till now no 😢 if ask about my period yes its regular. Do mamas think I should see doctor? Isthere such thing doctor can prescribe a medicine for my eggs? Im on folic acid too..
