<s>[INST] iv been on microgynon for about 6 months now and havnet missed any pills but have been late taking them a couple of times (only a couple of hours out) and have been on antibiotics once during that time but more often than not we use condoms as well. for the last 4-5 months iv been suffering from pregnancy like but still getting bleeding on the right days and only had negative tests so far (iv taken about 6 over the last 4 months), im wondering could it be the pill causing my symptoms or do i need to go get ChatDoctor blood test done. i would prefer to avoid the blood test since im phobic of needles but i need to know so i can try get prepered for 3 children if i am pregnant [/INST] Hello dear, I understand your concern. In my opinion there might not be any chance for pregnancy in your case. The following points favor the above statement:-1)There was no irregular intake of pills. Taking pill a few hours late doesn't alter the effectiveness of pills.2)You got the periods on time and there was no delay.3)All the urine pregnancy tests have been negative. Though antibiotics effect the birth control pills all the antibiotics might not do so. Only a few like rifampicin, rifabutin effect the hormonal pills. So relax. There is no need of any blood Chat Doctor testing. If there is any pregnancy it would show up on urine pregnancy test also though later than blood test. So nothing to worry. Avoid stress. Stress regarding the thought of pregnancy also makes one to feel the pregnancy symptoms. Hope this helps. Best regards.... </s>
