Cramping/Symptoms question?

Tabitha • My name is Tabitha I`m 25::Mama to my amazing son::Wife to my crazy husband:: Baby Number 2 due 7-18-2016 👩🏻👨🏼👦🏽❤️
The last time and only time I have ever been pregnant was in 2009...I don't remember how far along I was when I found out or my symptoms besides boobs were sore terrible morning sickness and exhausted lol  I'm 5 weeks though with this baby and I just found out Sunday I'm nauseous but haven't thrown up yet and my boobs hurt but I'm not as exhausted as I remember being with my son(yayyyy) the only thing I'm worried about is cramps I mean I know people say it's normal but it scares me I don't remember cramps with my son but I'm so scared of miscarriage I have never had one does that mean I'm less susceptible without a history of them I am 25 and was told by Drs bc of my endo I would need another surgery and probably other help to be able to conceive again but I did it naturally by surprise and I soooooo don't want to lose this blessing that took so long to get here 😐
