Could I be pregnant?

I had my last period october 27th and it ended october 31st my cycle starts every 28 days on november 20th i spotted light pink and brown it lasted 1day my period should of been on november 23rd i am 4 days late on november 27th i had unprotected sex on 2 of my fertile days but he pulled out each time my breasts ache now and then and mild cramping on my lower abdomin are these signs of pregnancy? I have been pregnant before but that was 10years ago and i cant remember how i felt

My normal Period is the 6th till the 11th and heavy day 1,2,3 and 4 then tales off the last 2 days..... this month I was 4 days late and the first day was extremely light spotting the day 2 was heavy, then just light spotting for the next 4 days. I took 1 pregnancy test on the 6th and it was negative then another on the 8th also neg. I have been feeling really sick and have had light stomach cramps (which I don't normally have) since the middle of last month. I have been having really bad mood swings, I'm also going to the loo more often and can sleep for over 12 hours and still be tired. Could I be pregnant or is it something else?

My husband & I are in our 15th month ttc. I had a laparoscopy in September to open both of my tubes, however my doc could only open one tube because the other is blocked by a large fibroid.

Anyways, up until this cycle, my periods after the lap were normal for me. Normal being 4 days long with a light first day, heavy days 2 & part of 3 & then light for the remaining day and a half. This one arrived 3 days early & has been very light for me. Normally I need a super tampon by day 2 & this cycle I have barely been using up the regular ones in a 6-hour time frame. I am now on day 4, so I'm winding down.

Does anyone here have experience with a light period & then being preggo? I have no other symptoms of pregnancy except being super tired. I took a hpt last Wednesday & it was BFN...period showed up Friday.

Recently my husband and I have started ttc again. We tried for over a year from October 2010 through December last year. We quit because we got a cruise to Mexico for Christmas and couldn't use it until September. So, we stopped trying and I also stopped tracking my cycles. While on the trip we started ttc again. We took the trip around the 23rd and I know I got AF about 2 weeks before we went on the trip. After the trip AF came October 9th, so I'm not quite sure what my average cycle is anymore. I've been looking at my past cycles and the shortest was 27 days and the longest was 36 days, with the average being around 31-33 days. Well as of now its 36 days and I'm not having any of the normal symptoms of AF coming. No sore bb's, no cramping. I've taken 4 99cent store pregnancy tests the most recent yesterday and they've all been negative. Today I'm suddenly feeling nauseous and I can smell my cats breath who recently has been acting strange. She's always wanting to lay on top of me constantly(like all day if I let her), when normally she will lay near me but will run away if I pet her, its almost like she wants to be treated like a baby. I keep having to push her off of me because her breath is fishy and makes me want to puke, but she keeps coming back. I've had my cat for 5 years and this is something I've never experienced with her before. I don't necessarily think I've tested too early so either I'm not pregnant or all of those tests are defective, but I'm definitely wondering because its already 36 days and I feel like AF isn't coming anytime soon both mentally and physically. What do you guys think? Any feedback is greatly appreciated.
