TTC 😔

Destiny
Hello Ladies 
I just got off BC (pill) mid February after 8 years I came on her cycle in February and in March, I had light spotting for 3 days in April which came early and nothing in May until the last day which was late. I have been having unprotected sex with my husband. Do you think that's normal for someone coming off of bc or should she get into the docs office for a pregnancy test? I've taken 3 HPTs and all are negative. 
If it's normal, how long did it take for you or someone that you know to conceive.Â
