Dont worry itd probably what your feeling but it will get stronger and stronger. U will know !
I am 19 weeks and i starting feeling gassy like movements or butterflies...but i have that feeling all day enough to know it is the baby. It feelts like something floating or so...its probablt ur baby. It is hard to notice except u r really vigilant
A fish swimming...its weird but so awesome!
Early on it felt like bubbles or butterflies floating around at about 12-15 weeks.....then as I went along more into the early 20 weeks...like a lot of wriggling in the tummy area..... lately its full on movement. ...arching her back, kicks arms moving about...I'm nearly 30 weeks on no.4.
I could only describe it when your stomach is churning like your on a boat.
