Hello. I Am Struggling To Get An Appointment At My

Hello. I am struggling to get an appointment at my local GP and in need of advice.
I am 35 years of age and was recommended the mini pill Cerazette. I am two week in on my third packet/month and have not missed any tablets within this time. I have been experiencing lower back pain, severe bloating and a very uncomfortable pain in my lower stomach for five days now, I have been bleeding for three weeks, which I know is common with this brand. I have conducted three pregnancy test which all were negative as I read theses symptoms could be caused by an ectopic pregnancy.

Many thanks
