Fixation...how can i just relax and say to myself...please enjoy happiness finally? pill,period,and

Hello,
I am having my first love relationship, even if Im 27.I am a fearful person, but my fears have increased in the last2 months.In august the condom slipped off,I took Norlevo even if he hadnt ejaculated;the period came with 2days of anticipation, then I started to take the Loette pill.Currently in the 7day pause I had the withdrawal bleed. But since 2months I have the fixation of being pregnant.I took the test before the bleed(negative).Ijust cant take my thoughts away from it.Im afraid that I wouldnt recognize a pregnancy in time for abortion.My questions:
1.what is the rate of bleeding even in case of a pregnancy?so withdrawal bleed isnt a proof?
2.who guarantees that 7days cannot originate a natural cycle?
3.I realize that this is a great mental problem, how can I feel better?
Thank you!

Been there!

hi wouldn't worry at all,i had my first relationship at 25,and yes all these things run through your mind about getting pregnant because i was the same way.if ever in doubt u just take a test,and stop worrying.Trust me you're not crazy because i was the same way.that feeling will soon die down, i wouldn't worry trust me.

Relax!!!

You really need to relax, this is all in the mind. If you have taken a test and it was negative - go to your doctors and have bloods and a test done there. This should put you at ease. You need to realise if you take safe precautions you generally won't get pregnant. My BF and I have used condoms for 5 years and I have never even doubted I may be pregnant as we are careful. So I am a living example of using condoms and not getting pregnant. The only way you can feel better is realise that you are thinking really irrationally and you also need to take all the precautions to make sure you are NOT going to get pregnant. For a start rule our pregnancy at the doctors surgery, get on the pill and use condoms - hey presto no pregnancy!
