I have a question.

I was supposed to start my period the 15th of April and I missed it. On the 1st of May I started my “period” but it was no comparison to what my last period was like. My last period was so heavy that I would bleed through a super plus tampon onto my pad and this time I could wear regular and super tampons with no panty liner. My period usually lasts for 5 days but this one lasted for 4 days. Today I noticed my discharge was clear and stretchy. Could that mean I’m not pregnant due to me ovulating or am I ovulating? My partner and I use the pull out method. I took pregnancy tests whenever I missed my period on the 15th and whenever I was supposed to get a blood test, I started bleeding on the 1st. I know you guys can’t tell me if I’m pregnant but I just want your all’s opinion.
