I'm now 31 weeks pregnant & i can remember plain as day when i was about 7 wks along, i had the same thing!!! It felt like a kind of pin pricking inside my vagina & would often get a dull aching feeling also. It continued for a couple of weeks & so did the lower abdominal pains on the sides of my abdomin! It's all just part of the stretching process that's going on inside our bodies
I also had a miscarriage previously.... last December, so i can understand your concern! The pains/aches on the sides of your lower abdomin are most probably Round Ligament pains, which are cause by the ligaments stretching as the uterus lifts up higher..... & it can also run all the way across the bottom also & be on both sides at the one time..... even higher too all over your stretching tummy
It's the beauty's of childbirth...... this is what we have in our favour when they're 16 years old & we're trying to guilt them LOL
Well goodluck to you both.... i found that a nice warm bath helps to sooth the aches & pains! Not too hot though.... you don't want to bake your little one!
All the best, Crystal xoxoxox
