I'm 19+3 and get period like cramps as well.. I told my Doctor at 15 weeks and he said it's normal. He recommended a heating pad to help ease the pain.
I had the exact some thing cramps at 9 weeks and cramps at 19-20 weeks. Baby would kick during the cramps too so I wasnt to concerned. They were period like cramps that only went away if I was laying on my back. They went away after a few days, I never got checked out for them, I guess it was just baby growing cause after they stopped I magically got fater lol
How did it turn out as I have had same and for weeks I’m 19 weeks 4 days today and go in for my 20 week scan Friday and have mild cramps on m off in the day and even now right as woke up on lower right side cramp inside and my doc says normal growth and ligaments and uterus stretch etc causes is to cramp more during these times but it scare me still daily and o just wanna make it past 25 week mark it has been a long week for me with them and I feel baby today
