Pain Help ?

I’m having pain on my right lower side it keeps happening every 2 mins or so for the last couple hours only last about 5-10 seconds it’s so painful only on one side I took my blood pressure bc I’ve got a headache from hell too yesterday I lost a good chunk of my Mucus plug I know it doesn’t mean much but could mean something I’ve not been feeling the best since yesterday either beyond tired just not feeling myself has anyone had this happen to them around 35 weeks not sure if I should try calling my doctor later today or not I don’t wanna end up going in for no reason at all posting a picture of where the pain is & my blood pressure I’m not sure if it could that or not
