Clarification on conception

[Annie9826]

So, to start I'm going to sound like a teenage girl who needs dr. Phil or the jerry springer.  Everyone has skeletons in their closet and I am for one regretful for this.

My husband and I (fiancé at the time) were trying to conceive. I have been on birth control -microgestin - for almost 5 years. I took my last pill January 27, 2017. I had my LMP on January 28th-February 2nd. We spoke to my doctor, she said it would take 3 months before I could get pregnant. My husband has been ejaculatig inside me since February 3rd. The morning of February 18th we talked and just felt we were very unsure if we were ready for anything serious together. We split up for a couple days(again fiancé at the time) The night of the 18th I went to a party. Where I met my friend. We got drunk. He had coke(which I never tried) but apparently he does it on a regular basis. I know drugs play a role in reproduction but I'm not sure which effect it has. But I did 4 tiny little bumps.  Went home, felt like ****... the whole spiel. February 19th we met up and had sex. He already has 1 child he doesn't take care of and a dui. I, myself, have never been introuble, you can say I'm a goody toshoos so this was very out of my comfort zone but felt I had to do it to find out what I wanted in my life. We did not use protection, jut the pullout method. I didn't enjoy it and never peaked. My husband and I got back together the 20th or 21st and we talked anout what we did and how we felt and of course makeup sex... which he did ejaculate inside me. And has ever since. We have sex 3-5 times a week and we are both very healthy people. I found out I was pregnant April 15th. I had my first U/S on April 25th and was given 6w3d that day, and December 16th as my due date . Today I had a bedside ultrasound giving me 9w4d which is still due date of December 16th. I never though I would be in such situation and I guess I'm just feeling a lot of guilt and need reassurance that I'm not an awful human being. What is the probablitly of this baby not being my husbands?:(

I guess that didn't show up very well.  What are the chances of the baby not being your husband's? Zero.

The February sex would not have given you a due date in December.  It was a month too early.

You broke up with your husband in February and got back together with him in February and now you are married?  That is impressively fast work.

ps -- Incidentally, saying "I felt I had to" [do coke and have unprotected sex with a deadbeat dad] "to know what I wanted in my life" is not a very realistic thing to tell yourself.  It probably occurred to you even at the time that doing this was not going to get you any nearer to enlightenment about your Life Path.  You wanted to have sex with the guy, you had sex with the guy.  

You're going to be a mama.  You're going to need all the clear-eyed honesty  you can get, for years.  Try not to kid yourself about why you do things.  Just be straightforward with yourself.
