the thing is, my boyfriend and i almost always use a condom when we have sex, but i have been on the pill for about 3 -4 months now, and we have slept together without using a condom about 5 times altogether. each month i have missed a few pills, but then came on as normal in the week break from the pill, but today i have started very slight bleeding, like a red-brown colour. it states that this is a side effect of the pill, but i have never had it before, only today! i have had the rest of the side effects eg-tiredness, nausea, but not bleeding. however, these side effects are also relevant as pregnancy symptoms and now i am extremely confused. but when we have had sex without using a condom, he has never actually came up me, he has always took it out and came then. ive heard of pre-cum but is there a likely chance that these could be pregnancy symptoms and not side effects of the pill. please help me im in a terrible state. thank you.
