Pregnant at 16

So I am quite obviously 16 and found out 2 weeks ago that I was pregnant. I didn’t think of it when I missed a week of my period just thought it was normal cause normally have quite an irregular period but I started to feel sick and just did I few calculations and quite literally shouted fuck, luckily was home alone. I FaceTimed my boyfriend straight away and he acted amazingly about it, I wasn’t expecting him to add oddly but anyway I still haven’t managed to even come across the situation with my family and don’t quite know how to. My boyfriend, of 3 years now(yesterday!!) told me that it was all going to be okay when I told them but I don’t have an easy home life. I fight with my mum 24/7 and my dad works away all the time, I have told my sister but she doesn’t live in the same country as me and the rest of my family. I’m so concerned and I keep thinking my mums going to know or realise because mother’s instincts are always so good and it makes me feel quite anxious. In the two weeks since I found out I’ve had 3 days off due to sickness but to my advantage a virus has been going around x

I’ve decided to keep my identity anonymous x
