Hi , just found out yesterday that i m pregnant and due in April if everything goes fine. I m 19DPO today and yesterday after POAS i got that i m 3+....  Should nt it be saying1-2 or 2-3?? What can it mean? Something wrong? Do you think i could have ovulated earlier? My chart is attached. Thanks,congratulations and may we all have a healthy and happy 9 months ☺️
