period like cramps

So for the last week on/off, i woke up with period like cramps and it was a good 4-5 hours. Did tylenol, a bath and recharged positions because it just was so bad then it stopped. My back pain hurt with it as well. My back pain stayed but was intermittent but my period cramps went away. It’s been like this for a week.

Now my boyfriend and i had sex last night, woke up with intense period cramps and the sensation going down my legs and just almost continuously taking my breath away and also bg with back pain. I haven’t been checked for dilation but could this mean that i’m dilating or just is this normal?? i know it’s not braxton hicks because i’ve had braxton hicks very early in pregnancy and monitored for them due to my history of my premie. I have had braxton hicks during all of this but not frequent or intense.

i’m 32 weeks. I have never made it this far in pregnancy due to my premie being born 13 weeks early
