Input?

Ive always had irregular periods but last month I totally missed my period. Last period was september 9-15 I missed my period in october 13-19 then spotted the 20th 21st and 22nd. I took a test the 26th and it was negative. Then had a spot on the 30th nothing since then. I downloaded the what to expect app and if I was to just get a really late positive id be almost 8 weeks. I havnt had any real symptoms but I was really wet for a week or so with almost watery clear discharge. I get the feeling that i want to throw up sometimes but I never do. Yesterday my lower back was really hurting but today its fine. Last night my nipples started hurting and that stayed. I was thinking about waiting the next 10 days to take another test or wait to see if I miss my period this month. I hate testing. Those negatives really get to me. Im still trying to convince myself that my period is just really late and its gonna show. Idk what im looking for on this post but if anyone has had a similar experience id love some feed back ❤
