i know how you feel my first pregnancy i was scared to tell my dad but the night i told him the worst thing happened i had a miscarriage and i regretted not telling him sooner but im 17 and 3 months pregnant with another one and i finally got the courage to tell him the night i found out if i was you i would because you need special care i was 2 months with the 1st when i seen a doctor. he may be angry at first but once he hears the heart beat he’ll change his mind.
