Period-like cramps?

Hey everyone, I have searched for this and found a few encouraging posts, but I just wanted to check with others who are possibly going through the same thing at the same time! Before I got my BFP, I was convinced I was getting my period because I had dull period cramps leading up. But sure enough, period never came and I've had blazing positives ever since! However, I'm now 5 weeks pregnant and while I'm not cramping as much as the week of implantation, I do get the occasional dull "period-like" cramp. Is this normal? I've had super sore boobs (and nipples!) no nausea yet, been abnormally hungry, and no bleeding whatsoever. Just looking for possible reassurance from those who have experience this and everything turned out ok or from those of you currently experiencing it!
