26 weeks bad experience checking cervix

Hi ladies. so a couple days ago i saw some blood when i wiped, just a tiny bit. i went in for my regular appt on Thursday and told my doctor about it. She got a urine sample for a uti which was negative, and then she looked to see if there was any blood. she didn’t see anything so she wanted to check my cervix to see if it was all the way closed. Right when she stuck her hand up there i immediately felt super nauseous and got cold sweats. I obviously didn’t expect it to feel good but didn’t expect it to feel like that either. She said my blood pressure probably dropped and sometimes that happens. Has anybody else experienced this? It also made me nervous if i can’t even handle getting my cervix checked how am i going to handle giving birth 😳 getting pretty anxious here
