TTC any advice ladies?

I am 25 years young. I am the mother of a 7 yr old. The pregnancy with him was a complete shock! I was 17 didn't know much about birth control. Needless to say took some penicillin and booooom I was surprised when I found out I was pregnant. Had a beautiful pregnancy and a healthy 6lb 7oz baby! 39 weeks later... Since then I have tried to have another child. Well my periods are abnormal. I period when my body wants too. I had my last period on the Monday following Mother's Day; it's now forth of July. Still no period took a pregnancy test 2 weeks ago; unfortunately it was negitive. But I'm not sure if it was to early. I had been taking vitex(natural pills to help regulate period)... I have had 2 days of cm thick white no odor. But I don't want to get my hopes up! Any ladies have any advise. Currently not taking any birthcontrol. Haven't used that since I was 17... Tia!❤️
