Contractions?

For the past two days I have had some pain in my lower abdomen and some in my back. Yesterday there was more pain then the day before. All started after my membrane sweep and stretch. It almost felt like period pain, which I used to have severe period pain. Last night I woke up to more cramping. Worse then during the day. Kept me up for a few hours. Tried to time them but found it hard to. Didn’t want to wake my husband up each time I turned my phone on and back off. Got up to use the restroom and a big chunk of my plug fell out and it had pink tinge to it. Finally was able to go back to seep. Got up this morning and now not having much cramps. Feel like I got excited for nothing. How to I bring them back on again? Anyone else struggling to time them?
