If you are and have been taking the yasmin for 2 weeks then it should be fine. I was on yasmin for 7 months and my boyfriend and I didn't use protection once. I hate condoms so this was nice lol

But my biggest thing is the overweight thing?? Should I let him cum inside me? Or should he pull out??

Honestly I really don't think it matters, but i'm no doctor. I weigh 160 lbs and it's never been a problem. I don't think you have anything to worry about.

Thanks so much! I was just curious as to whether or not, I needed back up... I do realize there is a small percent failure rate, but I take my pill exactly the same time every day and i'm not taking any medications that would interfere with the bcp.

First of all pulling out makes no difference. By that time he will have released precum which could contain thousands of sperm any way.

Before you are prescribed birth control your doctor should have given you a basic health check - weight, blood pressure, health history - that kind of thing.
S/he would not have prescribed you birth control if they did not think that it would be effective for you.
Being overweight increases the risk of blood clots but shouldn't have much impact on the effectiveness of the pill.

Double check with the leaflet in your pack and if it doesn't say that is is less effective over a certain weight then you shouldn't have anything to be concerned about.

So basically, there's no reason to worry about needing a condom? I take it exactly the same time everyday, without missing a pill.
So in theory i'm completely protected ( yes I still realize there's a failure rate)

Just one last question:
does the number of times we have sex and the number of times he 'cums' inside me have anything to do with the risk of pregnancy?
Provided I use the pill correctly?

Nope, none at all.

The pill works by altering the hormone levels in your body.
Technically it tricks your body into thinking it is already pregnant. This then means that you don't ovulate and that the mucus in the cervix is thickened.

If for some reason you do ovulate the thick mucus is unfriendly to sperm and prevents it passing through.
This is why there is a failure rate, because some women (rarely) ovulate and have a thinish mucus.

Taking the pill at irregular times/skipping pils and such can give fluctuating levels of hormones and so makes you more likely to ovulate/have thin mucus.
The majority of the failure rate of birth control is user error.

So long as you either began your pill on the first day of your period, or you have been taking it correctly for at least 7 days and that you continue to take it correctly, then you are as protected as can be by the pill alone.

Remember the pill doesn't offer protection against std/sti's so make sure your partner is clean before having sex without a barrier method of protection.

Oh and have fun when he gets here

Thanks so much kia!! I take my pill at literally 9-9:10 everynight without fail! So as far as that, i'm good!

Yeh, it will be alot of fun when he gets here :-d
