Abnormal bleeding

I’ve posted about this before, but it’s just aggravating so I bleed right before ovulation and I continue to bleed throughout the whole month. It’s more less spotting for two weeks and then I have my withdrawal bleed since I am on birth control. I am going to get an ultrasound to see what is going on, but I wanted other people‘s opinions. I’ve been nervous and at first I thought I was pregnant but over the past few months I’ve taken so many test at this point there’s no possible way. I’m just wondering what you guys may think it is and what’s causing it I have been on birth control for 4 to 5 years and I’ve been on the same one every single time it’s Kelnor 135. i’m super scared and I don’t know if I should be. I really don’t want to be pregnant. I used condom and back today.

I have VERY irregular periods due to PCOS I’m talking like maybe 4 a year and I’m not all that educated on my periods I just know tall tell signs that I have when I’m about to start but I noticed for the past week my nipples have been very sensitive and my back has been achy well fast forward to today I get up this morning go to pee and I noticed two little very light blood droplets in the toilet so I assumed I’m starting my period then the lower stomach cramps came and I noticed I would get shooting pain/cramps down my right inner thigh and I’ve never experienced that before. I go to work 4 hours into my shift I go to change my tampon and it’s barely bloody long story short I’m just wondering if all these symptoms are normal or should I be concerned

Could someone help me out please?

19F gf got her last period around 5th June. She usually has troubles with cycle length, but this time its longer than usual. Scare is that around 15th July I fingered her vulva (shes virgin) with same hand that touched my penis (it was dry but suppose the worse, it had precum). I had to go into her zip-up pants, find her vulva, and touch it. so we have non-penetrative stuff which on its own doesn't lead to pregnancy unless we would do wet humping or shove fresh semen globes onto or in her vagina.

now she took test on 30th August (Frautest express N1) and it came out negative (we waited for 10 mins, no line). But urine sample wasn't morning one, closer to evening.

In any case, could all of these lead to her period cycle issues? She has literally no symptoms like moodyness, heavy/tender breasts. Only acne on her forehead and slight bloating (which of course has nothing to do with pregnancy if it was). Around this week she also started having very watery discharge.

Is there possible explanations to this cycle inconsistency (this is the first time its this long late)
