Please help!!!!!

I am a high schooler with my first boyfriend having sex and I’m going to start birth control my next period and we do the pull out method sometimes. I’m super anxious and so stressed over this, me and my bf had sex on March 28th(5 days after my period ended) and we did the pull out method. My period is regular and most of the time I know when I ovulated because I have heavy clear stretchy discharge but I’m on cycle day 20 (out of a 30 day cycle) and I can’t tell if I’ve ovulated, I just discovered checking my cervical mucus… I haven’t really had any discharge(on my underwear) but when I did the self test with my finger

to check the CM this came out and it’s a little stretchy and slippery. Also I’ve been having like body aches but weird aches in my inner thigh area and kind of a pinching feeling in my lower abdo

minal area. Can someone please help me, I just really need to make sure this is normal CM and not any kind of early pregnancy thing. Also my cervix position seems pretty high right now.

Is this ovulation?!? I’m so worried please help!!
