Fertilaid! Quick question

Kara

So I’ve been taking fertilaid and ovaboost since September I feel that it works great in balancing hormones making my cycle regular and having ewcm to the point I know when I’m about to ovulate. I can easily test for maybe 2 or 3 days and bam a positive! BUT!!!! I’m still not pregnant. Should I quit fertilaid or should I switch to something else?!!!! Idk what to do at this point and I’m depressed
