I was wondering if someone could give me an opinion or some guidance on my situation.
Basically, I had sex for the first time a few weeks ago (2nd October, specifically) and we had used a form of contraception (Condom - I would have used something like the morning after pill as well but the experience was unexpected and I honestly didn't really think about it). However, about two and a half weeks after this I have been experiencing a bit of pain in my lower abdomen (not a usual symptom before my period), bloating and frequent urination.
Around the time my period was due (23rd-24th October), I have experienced some bleeding although this is not much like my usual periods since it is much lighter than normal (although the blood is still bright red, rather than a brown/pinkish colour), so my thought is that it is possibly implantation bleeding. My frequent urination has also stopped at this point and I have started to get pains in my lower back (which is a usual symptom I have when having my period). My bloating is still prominent but it seems to fluctuate (e.g. sometimes it's quite large, whereas sometimes it's reduced in size but still noticable as bloating).
As a result of all of this and despite not having experienced other symptoms of pregnancy (changes in breasts, sickness, tiredness, etc.), I have had my suspicions that I am pregnant so I bought a two tests to see the outcome. I used one of them yesterday (I felt comfortable doing the test then since it has been over 21 days since I had sex) and the result came up as 'not pregnant', but I don't feel convinced that this is the case, since I can't see why else I would be experiencing such symptoms (unless it really is my period and it's just late/affected by stress? I did also read somewhere that becoming sexually active can interfere with your pms, but I'm unsure as to what the accuracy of this statement is). I do plan on taking the second test in a few days when the light bleeding I'm experiencing has stopped since maybe the hormone detected by pregnancy tests isn't high enough yet (or, unless I seem to get bleeding that resembles my period, then after that). I would just appreciate some input on the situation is all, especially if someone has experienced the same (would be interested in knowing what the end result was, whether you were pregnant or not).
