Need advise

Vicky

I’ve always had regular cycles, only recently I was late on my period, so being a week late I took a test which was a very faint positive. I was having other symptoms such as ovary and uterus pain and cramping as well as sore and tender breasts, and feel nauseous. Due to the test being faint I decided to take a couple more which were negative so went to see my gp and they were negative too as well as my bloods. A few days later I then had my period. However, I’m due to ovulate in a couple of days but have no signs of this, but struggling with abdominal pain, mainly on the left around the ovary area and bad back ache. Worried this may be something more like PCOS or possibly endometriosis as other family members have this. I could just be over thinking things but has anyone else ever experienced anything like this?
