Harleigh • mommy to an angel baby 😇 pregnant with my rainbow baby 🌈

okay I've never done this so please excuse the way I may word things.. I'm 19 years old and I've never had a REGULAR cycle until about July of 2017 (18yo) so when all the girls I went to school with started having their periods at 13 & 14, my initial thought was I can never have babies. well one night, (after I have been bleeding for about a month straight) i told my boyfriend that I needed to go to the er.. I just felt like I NEEDED to go. so, around 7 pm on September 9, 2017 we made our way to the hospital. shortly after we got there, they did the regular pee test and got me registered and then they called me back to the room and informed us that we were pregnant. 😍😍😍 I didn't know how to feel. it was an overwhelming happy feeling filled with love. but I was also super concerned because I have been bleeding for damn near a month, so long story short after a long week of constant doctors appts, on September 11, 2017 we found oit that we miscarried. well after the miscarriage, I didn't have a period AT ALL until this month about 2 weeks ago. me and my boyfriend are still trying and I just don't know what do think or what. should I be worried? has anyone else experienced this or something like this ? Please help...
