Stressing

My boyfriend and I have sex with just condoms and when he comes he pulls out. I don't know wether I should be worried but I am supposed to get my period in like 4 days bc I ovulated on the 18 and we had sex on the 19 and 20th and on the 8th. I am just worried because I had white discharge ( I didn't know if it was just normal vaginal fluid or not) and my boobs hurt really bad, I have acne and I am constipated ( which happens around my period too) and I took a test yesterday and it was negative. I think I just worry too much but I was wondering if I should take another one or just wait.
