I just don't get it?!? 😬

lm trying so hard to not stress about getting pregnant. But it's so hard due to us wanting to have one more.. I just started bbt due to me going to the doctors. My period has not started yet and don't have any signs of it.. my periods have irregular for over a couple months so my doctor said to start bbt till I get my period to get into the routine.. well I know my body and when I seen EW CM I started doing OPKs and got positive results. I've been feeling really tired headaches and cramping but different feeling then period cramps. I've been getting dizzy with getting up and just over all tired. I don't know when I should test I don't know when my period is suppose to come. Glow said May 30th and nothing yet. My breast have been hurting for over two weeks. I took a test and it was negative but I know it's probably to soon. Can anyone help me and tell me what my chart is doing please?!? I just need a few  comments. I've been on the internet looking at things and I'm not really getting any answers. Yesterday I started with white discharge. My nipples hurt too.. please if anyone can help me I would really appreciate it!!
