Maexeni pill and a latex allergy

I have sex regularly with my partner and I haven't had any pregnancy scares since I started using this. I am quite meticulous about taking the pill every day around the same time, so I'm unsure of the efficacy if not being very regular with the pill. As far as I know, I have no symptoms due to this contraception. I have developed a latex allergy since I started taking this contraceptive, but this could be unrelated? Haven't been off it since latex allergy developed so couldn't say for sure. The only thing that really worries me is that I'm a smoker and I know estrogen increases my risk for heart attacks and blood clots - I have spoken to my GP about this concern and was advised that this would only become a huge issue in my 30s
