Hiya hun, I know exactly how you feel, I had this problem missed a period had loads of pregnancy symptoms and bfn after a week I saw my doctor who did a test (didnt think I had done it properly
) when the test was negative he told me to wait two weeks test again and come back, again bfn this has been going on for awhile now, I am still having pregnancy symtoms sickness, tiredness etc but have had a light bleed for my next period my doctors are sure now that I am not pregnant and are trying to find out what has caused my hormones to be all over the place, I have a scan tomorrow so hoping to get some answers, but had a month of the doctors saying I may be pregnant and to watch what I ate etc and the not knowing is a nightmare so know how frustrating it is and what mind games it can play on you!!!
This is what pee on a stick says about the chance of having a false negative hope its of some help to you
Can I still be pregnant if the test is negative (have a "false negative")? In a word, yes. You could be testing too early (before your baby is making enough pregnancy hormone to be detected by the test.) And some women (this is fairly rare, but possible) never get a positive urine test even when they're definitely pregnant (for some reason the hormone doesn't make it into their urine.) I have a friend who didn't get a positive HPT until 25 DPO! (With her second baby, a test at 23 DPO was negative . . . but a test on 30 DPO was positive. Oddly enough, with #3, her positive test came at only 12 DPO.) If you get a negative test but think you might be preggo anyway, wait a couple of days (giving the hCG hormone time to build up) and try again. It's not over until the fat lady sings-- and your period crashes the party.
If you are not monitoring your fertility in any way (OPK's, charting cervical mucus or basal temperature, ultrasounds) it becomes extra-tricky. There are two parts to every menstrual cycle: from the start of your period to ovulation, which can vary quite a bit in length, and from ovulation to your next period, which is usually consistent in length. (This second half is known as the "luteal phase," and the normal range is 10-16 days. It's normal for your typical luteal phase to vary by a day or two. For example, mine is normally 11 days, but 10 and 12 are not unheard of either. I have also had a couple of longer ones by total fluke.)
Because ovulation can happen at any time, it's possible your egg was delayed for some reason (stress, illness, travel, excitement.) This doesn't mean your period is actually "late" (it could arrive within the normal 10-16 days after ovulation), but rather than your entire cycle was delayed due to a later-than-usual ovulation.
