Hi OP, so sorry you feel the way you do. Sending Hugs ❤
What you are experiencing sounds perfectly normal to me. I'm currently 14+6 days and during the early weeks, I did experience weird twinges like you describe. It was just off and on, maybe a couple twinges a few times a week, nothing major. Had a few since then too. To be honest, I didn't really monitor it to much. I knew it was down to my insides changing and making room for baby.
You need to remember that every body and every pregnancy is different, so what some people may experience one type of way, you may be completely different. It doesn't make your experience not right though, or that it indicates that something is wrong.
For example I have had bad morning sickness, nausea, tiredness and fatigue from around week 7. It's only just starting to settle down!!
As PP says, what you are currently experiencing at 5/6 weeks, sounds normal and definitely early pregnancy signs. Especially the sore boobs and twinges.
I know it's easier said than done, but try not to worry. I have a mc last year, and this whole pregnancy, I have been very anxious and nervous. But I kept reminding myself that today, I am pregnant and there really isn't much else I can do to control any outcomes.
It doesn't sound like you've had anything happen to indicate anything is wrong, so try and stay calm and enjoy the sickness free days! 🌷💕
