Please tell me !

Wanted to ask for other mothers or pregnant women for their opinion.

My partner and i have been trying to get pregnant for about 5-6 months now...  i have a 26 - 28 day cycle and my next period is due this Friday, if i was to be pregnant i would be in my fourth week according to my phone app (haha) i have been taking per-natal vitamins and have been eating healthy etc...

I didn't notice at the time but my partner and i were sexually active for the 3 days i was most fertile and ovulating. it has been over a week now and my breasts are quite tender.. like im about to get my period but usually it would of only lasted 1 or 2 days not over a week. and its getting to the point now where they are really noticeable. i have been really tired too, struggling to concentrate at work and im going to bed around 8 - 8:30 just cause i feel as though i cant keep my eyes open.

and for the last day or too im starting to feel slightly sick to the stomach .. just a bit off if you know what i mean .. hard to explain .. and im getting a very watery/clear discharge.

Could i be pregnant ? if you have had similar experiences please tell me :)

Thank you
