after my HSG i was told my tubes are blocked i started using serrapeptase in December in january i got my very first faint line 11dpo which startd faiding by 13dpo and my period was late by 3 days for that cycle, i never went for a blood test so i wouldnt know if it was a chemical or just faulty HPTs i dnt know wether to believe the serrapeptase worked but i got abit of hope from that experience, anyone else ever tried serrapeptase id like to hear of ur experiences?
