Could I be pregnant?

I was holding off to write about this because I figured it would come. I was due for AF on the 15th/16th of August. I am an extremely regular person and always get it when I'm supposed to, and I have not missed a period in 10 years (I'm 20, btw). Either a day or two before I was supposed to get AF, I noticed what looked like a spotting of redish-pink blood. I had it for maybe a couple of hours, then it went away. Never got AF. I am now about 8 days late. For the entire past week I have been very, very nauseous all the time. I've had some cramps, but they are nothing like my horrible menstrual cramps that I'm used to. In addition, my nipples are driving me nuts with the sensitivity, I pee every hour and I feel constantly bloated. It feels like AF will be here any minute, but she never comes. I have no idea what this could be, but pregnancy has crossed my mind, even though I've gotten two negative tests, one of which I took this morning. Any advice or previous similarities would be greatly appreciated! Thanks :]

We've been TTC for 6 months and every month prior to has been the same: no signs of PMS except fatigue and then AF comes. This month, I've been incredibly tired, I crave foods I would never eat (like seafood), I have cramps (and I haven't had cramps in over 10 months), and also some spotting. I know those are some signs of PMS but also pregnancy. AF is due 8/23 & since we've been trying, it's been right on schedule. Did you have any symptoms that you were pregnant?

Been TTC for almost 16 months now. With irregular periods, it's not been easy. LP was 7/17/09, had mittelschmertz on 8/3-4/09(BD on 8/2 and 8/4), and then 8/10/09 I got really dizzy, nauseas, was sensitive to light. Scared to test, don't want a negative result again. When should I test?

Well right now I am in the TWW, and had my CD 21 blood work done this morning. The nurse & then doctor called to tell me my P4 level came in at 82.8 and to test in a week. I did clomid 100mg on CD 3-7 with Estrogen and did trigger shot on 8/8/09 and ovulated on 8/10/09. The nurse & doctor said this is a very very good P4 level. Just curious to find out how good this is and could this be a sign that I may get a BFP. Can anyone let me know if they got their BFP and had numbers this high on CD 21? Thanks!

6 days late!! done a few pregnancy tests over the last week and got neg's..?? wat do you think x

I am beyond frustration at this point. My period is late. I am not even sure of that because my cycles are irregular. But I have had sore breasts for 2 weeks now and they are killing me. I have taken pregnancy tests and they all come back negaative. I haven't really had any symptoms except for sore breasts and vomiting when I go to brush my teeht and feeling like my period is about to come off and on. This stinks and I am fed up!!!!
