trying to get pregnant for 7 months now

Been trying to get press t for about 7 months now. My period was super off and I haven't been on birth control for at least 10 11 months... I have 2 children already and never had trouble getting pregnant with them. Although I am not with the kids father I am with someone who I haven't had a kid with yet. In November I took an ovulation test and discovered I wasn't ovulating so I went online and purchased these fertileaid pills been taking them since beginning of January. I took an ovulation test this month and was ovulating so me and my fiancé tried again. I took an early pregnancy test 6 days before my missed period and of course it was negative yes I get that it might be to early for a test but I'm super anxious. Has anyone used the pills before? I need a little advice and some insight please
